Yep, now a days you need AT LEAST 512mb of ram. Upgrade that to 1 gig or maybe 2, ram makes everything run better/smoother. Also, GPU is a must, try to get at least a 128mb GPU, ATI, Nvidia... there good. Myabe if you can get a new motherboard you can get pci express for the gpu... unless your mb already supports pci express. 16 pipelines......... nice the 7800gtx is very nice
