Hi everyone, I would like to ask you how well my pc can handle this game Gears of War:

OS: Windows XP SP2

Amd athlon 64 xp 3500+

2gig ram

XFX 8600 GT/620 XXX

On what settings can I play this game? I'm expecting to play it on high so tell me what you think.

Not Even close to being able to play on high, i cant even play on high wit out the screen freezing on me every now and then and my specs are....

vista premium

core 2 duo 2.66

2gb ram

Brand new eVGA 8800GT

2 10k raptors in raid

but you should be able to play the game, who cares if u can max the settings out anyways
