I just built a new pc to replace my 4 year old one.
Corsair Obsidian d550 ATX case (great ventilzation/modularization
Corsair AX750 Gold Series Power Modular Supply
16GB ram GSkill Ripsaw
asus sabertooth 990FX R2.0 motherboard
gtx 650 graphics (384 gpu but no sli - I don't do games but this is a great card for $90)
I run Ubuntu 12.10 64 bit and it really runs great on this machine & cpu !
Last nite I had 15 simultaneous video conversions (avi to mpeg4) going using the Handbrake app and the AMD 8350 wasn't breaking a sweat as I was still able to watch a netflix video & browse the web at same time. Those video conversions finished in about 20 minutes. On my old Quad core AMD 940 that would have taken well over an hour at least.
Of all the parts of this build I really have to say the Corsair D550 case impressed me the most. It wasn't the most expensive part of the build but geez Corsair "really" did some great engineering on that Case. 2 front intake fans, 1 rear, both sides just push a button to remove, front face can open either direction to access DVD or other drives, modular no-tool drive mounts w/vibration damper snapon connectors and 3 more fan openings (2 top and one side) if you need them.
As to Win7... I just tonite tried to boot Windows 7 ultimate but it blue screened during boot.
NOTE though that my disk with Win7 ultimate has NOT had any updates/patches applied since Win7 was first installed on that external eSata drive. I am suspecting that I just need to update Win7 and perhaps Microsoft will have fixed whatever is causing the problem. I had already read that Win7 had a problem with the 8 core cpu w/out some patch so that will be checked later tonite.
I got the AMD 8350 because I do a lot of virtualization and having the extra cores means I can run more virtual machines simultaneously when doing "work" related stuff.
