my bro has a dell demension 4400 he plays wow in my grandmas basement using a 128 mb ati radeon 9200 4x AGP, run's great.bought at yard sale for $20. i just bought a nice biostar p4m80 motherboard for my case which i am using right now has 160 gb sata hdd, ddr2 1gb of ram. i just bought a new 480 watt psu, the one i am using right now is a 230 watt psu i pulled from an amd based computer (dose not support p4) so i wired it up so it does. the downside is that i cannot play WoW with normal fps it's like 16fps ;lol because i have no video card all i have is Integrated s3 unichrome. w/agp 8x . what kind of video card should i buy?
