I am finally upgrading from my old Dimension 8100 which I believe had a Geforce4 in it. I was wondering what are the cheapest cards I can get and still notice a big difference in performance. I am not a big gamer at all so I dont know what I need exactly. Is it even worth it for me to get a 6600 or can i go even lower and get like a 5200? i dont want to spend much, but i dont want to get a card and immediately think it sucks (my new build will be agp by the way)
