I just purchased a new motherboard and chip. I went with the Asus motherboard with a Athlon64 3000 with 1gb 3200ddr ram. I don't really play any games, but might want to try out a couple new ones like Doom3. I currently have a ATI AIW 7500 with 64mb and was wondering if this video card will work for Doom3 or not. I will upgrade if need be, but I don't want to drop a lot of coin. What would be a good one to upgrade to if I need one. Would a ati 9700 work good?
