My brand new HD 7850 just arrived :)
I was postponing the decision for too long in part because I'm just lazy. The sheer thought of having to change PSUs between computers made me shiver and avoid the decision.
My i7 3770 powered desktop is running on a 400W OEM PSU while my 525W Enermax 82+ PSU is being used on my lower power server which doesn't make much sense - all thanks to the desktop case not having space for the Enermax PSU due to the case's awkward design. So I'm in the process of change hardware around pretty fun stuff -.-'.
The promise of higher FPS in Team Fortress 2 won me over so I Mann'ed upp (TF2 pun) and ended up ordering a PowerColor 2GB HD7850 PCS+. Why this particular model? Well low noise and availability of 2xDVI (my monitors support VGA and DVI only) were the factors I valued the most while researching of alternatives. So I ended up going with the PowerColor 2GB HD7850 PCS+ after reading several very positive reviews in which it presented the lowest noise.
As to why the Radeon HD7850?
Normally I'd go for nVidia cards as I had good experience with them in the past being great both in terms of performance and Linux/BSD support. However this time around I'm into virtualization with VGA/PCI passthrough and nVidia cards expect the Quadro variant just don't support Xen (and other hypervisors for that matter) properly. The trade-off is that AMD doesn't support BSD so I'll probably passthrough 3770's HD4000 if I feel like having FreeBSD on the desktop as a domU.
With Valve's pressure on AMD regarding Steam being ported over to Linux I'm hopping that AMD own drivers mature making this a good buy in the medium term. For the moment I'm playing TF2 on a Windows 8 domU off Intel HD4000 so has soon as I get my hands on the AMD card I'll fire assign the HD7850 to this Windows domU. Afterwards I'll whip-up a Linux domU and check-out Steam and TF2.

Update 26/10/2012:
I've finally published my notes: HowTo: Xen 4.1.3 Windows 8 HVM domU with Intel HD4000 VGA Passthrough on Debian Wheezy
A month has passed since I got the new hardware and I have some novelties to share!
First I got XEN VGA Passthrough working and surprisingly it turned out to be quite easy to setup and I'm pretty happy with the results. I managed to passthrough the i7-3770 HD4000 integrated GPU, USB 2.0 Controller, HD Audio and secondary Ethernet to a Windows 8 Preview domU HVM on a Debian Wheezy dom0 using the xm toolstack. In the domU assigned USB controller I've connected an additional keyboard and mice.
As I only have the integrated GPU and no discrete graphics card I have to SSH from my laptop or use Putty from within Windows to control the dom0.
Now for the observations and quirks on Xen PCI Passthrough:
There's still so much more to be explored but Team Fortress 2 is sucking my free time :(

Now for the observations and quirks on Xen PCI Passthrough:
- During Windows 8 installation some artefacts appear but these didn't prevent or difficulted the installation process.
- Un-plugging and plugging the USB keyboard and mice didn't affect stability expect on one occasion where graphical artefacts appeared in Windows though I suspect this could be from the DQ77MK USB 2.0 "fast charge" ports. I have on my TODO list to passthrough another controller to double-check.
- Windows 8 Preview complained twice about crashed video drivers but its stability wasn't affected and the OS automatically reloaded the driver. One of these situations occurred after I kicked the power connector where I have ~8 power cords connected (this was one of the 2 situations were visual artefacts appeared in Windows outside of the installation process).
- Wolfenstein: Enemy Territory performance was crap having scored ~59 FPS in 5 timedemo runs. I have to further research the poor performance though I have a few suspects, however it could turn out to be something with the OS so I'll need to install Windows 8 on bare metal (brrr...) to compare.
- I really need to run some benchmarks using common tool such as 3DMark and Phoronix Test Tool and compare the VM performance with bare metal.
- My Windows 7 install media is corrupted so Windows 8 Preview ISO was used
- Sound works perfectly.
- The second Ethernet is running like a champ.
- Boot speed is reasonnable especially taking account that the VM is stored in a 9 years-old HDD.
- Came across some Windows repair boot menus. Either I'm too trigger happy to kill the domU when I see "lengthily" boots or shutdown (from both domU or using xm destroy) or there really are some issues. Will have to look into this in the future.
- I still have to passthrough another USB controller to test if USB pen and such are properly registered in the domU.
- The dom0 stability was never affected.
- Steam and its Source engine games work just fine having scored ~209FPS in Source stress test (dunno if this is good or bad has I don't have a bare metal comparison baseline).
- I've clocked more than 5h on Team Fortress 2, Counter-Strike Source and Day of Defeat. No issues aside from being hooked on Team Fortress 2 -.-'
- I'm impressed with Team Fortress 2 graphics, smooth performance and gameplay.
There's still so much more to be explored but Team Fortress 2 is sucking my free time :(

Ready...
Finally got all the hardware pieces for my new workstation: i7-3770 (non-k), Intel DQ77MK and 32GB DDR3. I'll be unwrapping and assembling them in the the coming days though most likely that will be only on Friday :(
These will go along with 2x 200GB SATA Maxtor HDD and 1x SSD Intel 330. For the moment I'll keep the PSU and case but most likely will be getting a new PSU (and probably case) in the future as I want to keep noise and power consumption as low as possible.
Depending on the power consumption and my ability to setup a proper XEN/KVM environment with PCI pass-through I might decommission my FreeBSD server and virtualize it.
The coming weeks I'll be messing with hardware settings and benchmarking. In late August I expect to be able to have an initial XEN/KVM environment with VGA pass-through for ET.
The new workstation setup should be able to:
To have everything running it will takes ages, most likely years due to both my availability and knowledge gaps.
Big challenge!

The new workstation setup should be able to:
- Run Wolfenstein: Enemy Territory
- Benchmarking with my demo should give at least 120FPS else I'll have to look into getting a dedicated GPU
- Should run on x86_64 in bare metal though as I've blogged early I doubt this is possible
- Should run on Linux/FreeBSD x86_64 or i686 under a VGA passthrough VM
- Run 5 VM concurrently
- FreeBSD VM as a testing ground for my FreeBSD server
- General purpose VM for web surfing, adming and gaming running Linux (CentOS, Debian and Gentoo are the likely candidates pending HD4000 driver availability)
- CentOS VM as a testing ground for my laptop and rpm package rebuilding
- Linux VM for security purposes
- CentOS or Debian host
- File-sharing FreeBSD VM with direct access to disk controller with PCI pass-through running Samba/NFS, SSH and OwnCloud. This would imply adding my 3x 1TB SATA HDD and most likely upgrade them to WD Red HDD and going for ZFS
- Router VM running on one of the two NIC provided by the motherboard. This VM could be CentOS, DD-WRT or OpenWRT
- Personal CentOS/RHEL repository
- Run ET, RTCW Demo, UT and Ventrilo servers
- Play Doom3, RTCW (online) and Wolfenstein: Quake Wars (online) with stable 100FPS
- Segmentation of VMs (DMZ, different LAN segments, etc)
To have everything running it will takes ages, most likely years due to both my availability and knowledge gaps.
Big challenge!

The desktop revolution has started...
... at least for me as I'm finally upgrading my Athon XP desktop from circa 2003!
It sure is about time ;)
These days my web surfing and administration of local network computers is performed on my Dell D620. It's quite a nice machine specially after being upgraded with Intel Core 2 Duo (15€ !!), 4GB, 128GB SSD and HDD drive caddy. It does however lack the graphics card to power Enemy Territory.
For my gaming needs I kept using the old desktop, however the bastard is noisy and has been overheating, so much that I had to drop from 2200 to 2000Mhz so that I can actually compile anything without segmentation faults errors.
But if it were only because of ET I'd keep the bastard. However I long for full blown virtualization, the kind that let's me run 4 machines without sweating, the kind that will let me passthrough PCI devices, the kind that leads me into spending hard earned money :(
The old Athon XP crawled under GNOME3. YouTube movies and Flash websites were choppy. Compiling world in Gentoo took ages (LibreOffice and Firefox have long been the bin kind). On FreeBSD I had to start using packages instead of ports due to the time (and electricity) needed to compile ports. On top of that it meant x86 and no x86_64 and KVM fun.
Also, in the past months I'm getting more and more interested in XEN and KVM namely their VGA and PCI passthrough abilities with proper virtualization instructions from the CPU. Both Intel and AMD have solutions for this however this time I've elected Intel.
I ended up with Intel due to lower power consumption, overall better performance, GPU with more-than-enough-for-ET performance and opensource graphics driver. Funny enough what tipped the scale was the power consumption and opensource graphics driver.
The selected weapons of choice were i7-3770 (non-K), Intel DQ77MK motherboard and 32GB DDR1600. I've placed online orders for all except the i7 but I'll take care of that until the end of the week. To ease the expense I've already started selling all the computer parts I have laying around (DIMMs, SO-DIMMs, graphics cards, NICs, etc), so far I've already scored 50€ with more in the pipeline - not bad.
I'll move my laptop SSD to the machine and re-use my old case and PSU for the time being - though those SeaSonic fanless PSU are damn appealing!
The decision for the non-K 3770 was rather simple: I wanted a fast, energy efficient and muticore processor and this version has that and VT-d support. Combined with XEN and KVM, VT-d means device passthrough to be used directly and natively in the virtual machines.
To guarantee that VT-d is supported I've chosen the Q77 chipset as it has100% guaranteed VT-d support. Some Z77 motherboards have VT-d support however it is un-official as Intel pulled VT-d support from Z77. I didn't want to take any chances so I went for Q77.
Why Intel's own board instead of ASRock or ASUS? For a few reasons: documentation on the Intel board is simply superior, 2x DVI, mSATA and mini-PCIe. Though I wanted the 2x PCI slots from ASRock and ASUS offerings I wanted to keep an eye on the future and for that the extra PCIe slot is better (though that eSATA port should really have been another normal SATA port Intel!).
Now let's just wait for the parts and assemble the machine ;)
