Sammy, keep the 4870. I have used both Nv & ATI back and forth for the last 4 yrs. ATI has better IQ and the colors look better as well. Before anyone starts preaching that Nv has come a long way with thier IQ and/or are even with ATI. Pfft, I can still see a difference. Maybe negligable but I can still tell. If you have new vid cards, you will eventually get a new proc & mobo, guarenteed, this is not underachivers.com and you are no wussy mod (unlike cw823). Aheem, having said all that, keep the 4870, its a smoking card.
Yeah yer rez sucks but that also can be improved. One of my buddies 73yr old just bought a sweet refurb Dell 24" LCD for $239 shipped! Dang, you should get one of those too.
