ok so thik you culd afford something like this?
CPU: Core 2 Duo E6300
RAM:G.SKILL 2gb DDR2 800
mobo: ASUS P5B
or gigabyte DS3
Western digital 250gb STAT2
Antec TruepowerII 550w
or TT soprano
and if you want a new video card, cause you should update soon:
im pretty sure it's the best card for the price.
if the price is too high, you dont need the video card, you can get 1gb of RAM and upgrade later, or you can get a smaller hard drive.
this sytem will last a while, a good 2 year, but tward the end of 2 year alot of stuff on mostly low settings, like crysis.
