I can play **** near any game on high settings, without any problems. It'll come with Windows 7 Ultimate 64-bit. Anyway, the specs :

AMD Athlon X2 5200+ 2.7Ghz (Overclocked to 3.0Ghz)
ASUS M3A76-CM Motherboard (Onboard LAN does not work)
4GB DDR2-800 (4 x 1GB sticks)
Sapphire Radeon HD4870 512MB (Has an aftermarket Scythe Musashi VGA cooler installed, and comes with the orignal cooler)
320GB Seagate Hard drive
Optiarc DVD-/+RW drive
550W Rocketfish Modular PSU (500W Continuous)
350W Antec PSU (Fully capable of running the entire system as is, and makes a GREAT backup)
Logitech Wireless Keyboard and Mouse
Logitech USB Headset
Logitech MOMO Racing Wheel

Case is not a good case. It's an OEM Emachines case, so that may need to be upgraded...

I'm asking $550, $300 + trade for Xbox 360 (20GB+) or PS3 (any version), or straight across trade, if it benefits me. I can include a 19" LCD Widescreen at additional costs.

Just random prices, all is definitely best offer... Not including shipping on those prices... Don't low ball me.
