mobo (mother board), psu (powe supply), at that resolution, it will be overkill to buy an gtx core 216, at least thats what i think, cause your processor will be a bottleneck for that card, i think an ati 4850 will be a good choice and only costs around 100$
motherboard = asus m2v-mx veryold one i guess :S
psu = iduntknow here to find that :S
alright can i be able to play 10.1 directx games nfs shift or such with this card and configuration ?
and what about gtx 250 ???
