I'm thinking of upgrading my video card in a little bit and want to go with an ATI card. Anyone have an suggestions? My budget is about $150 give or take about $20-30. I want to be able to play the new generation games i.e. Doom III and HL2. Should I wait to get a card until they come out? Also, is it wise to buy cards like these at computer shows? There are a couple near school and I'm thinking of stopping by.
