I try to build a new PC every year with a $1000-1500 budget, selling my previous one for about half. I've found this practice to be the best economically and for performance.

Also got a wireless Xbox 360 controller adaptor

Running Windows 7 Pro x64 (got for free through my uni when I was a student) and dual boot with Ubuntu 10.

Apart from the case and the GTX 460, which I bought last summer, this PC has so far lasted me since summer 2008. Pretty damn good, I think!

I was happily playing the Crysis 2 demo on Advanced and 60fps was no trouble. hardcoe (as it was known then), was a bit too blurry for me, and the fps also dropped too much, so Advanced was fine with me.

Is it sad that I'm going to get up extra early tomorrow morning before work so I can have a go on Crysis 2 for an hour?

I wont post my Gaming rig because its pointless for this game.. It seems to me it was made for my laptop.
2.1Ghz Dualcore {intel} 4 gigs of ram Windows 7 Ultimate {64 bit} and a tiny little 9600 mobile GPU {1 gig dedicated ddr version} An acer Aspire 8730

Framerates in the high 30s , and is just as dissapointing on the tiny screen as my gaming rig

game runs like a dream!

Right now:
Core i7 920@3.6ghz
12gb DDR3 @ 1600mhz
GTX 295
2x OCZ Vertex 2 SSD in RAID 0
24" 1920x1200 monitor

In a few days:

8GB DDDR3 @ 2000mhz
2x GTX 570
2x OCZ Vertex 2 SSD in raid 0 (taken from old build)

Sadly this new build wont really be needed for Crysis 2 as there's no DX11 and its not all that hard to run in the first place.

mine's on my profile page i think

Not as awesome as to what you guys have but i'm able to play the game at very high settings as well as serves the purpose
for my demands.
