nVidia GeForce 9800 GT/GTX/GTX+
Or take my Brother nVidia GeForce 9600 GT

doesnt look that bad...
4.0 shader model
812 mb's

your real problem is the ddr2 ram and the dual core 1.8ghz processor.

alright i have 6 gigs for ram and i am screaming fast. i would get at least 4 gigs of ram. If you got some money i would go nvidia 9800 GTX and doule it. (get 2) if not just go for one. if you cant afford that get a 8800 GTX then. hope this helps

DONT FLAME, i am basing itoff my experience

why not any GTX's????

so are you not PCI express??? be more clear

You should be good to run a GTS 250 1GB
This card can run every game and more that recommended specs
GTS 260 is good too but for the quality/price I say GeForce GTS 250 1 GB

i've got a nvidia GeForce 9400m with 512, and it can run pretty much everything out there pretty easily.

i guess its a special thing they manufactured for apple, but whatever is equivalent to it, get that...

dude just get a 9800gtx and youll be golden

for the same price, get an xbox.
wont have to upgrade til the next one comes out (4-8 years from now)

@topblast, i dont believe so. i guess i am not up to date with my VC's
@Corndog, computers are a hole heck of alot better bro

your brother is right, then get the 8800gtx. that can still run every game and will be able to for a few more years
