I currently have Intel 2.6GHz with 1.5GB ram, with an ATI Radeon 9800 Pro AIW 128mb, and wanted to upgrade my card. I mostly play FPS (HL2, CS:Source, FarCry, and soon FEAR...). My board only has AGP, so PCI-E is outta the question. My budget is about $250-$300 max. I kinda have my eyes on the ATI X800 XT AIW 256mb. How much of a gain will I get if I upgrade from 9800 Pro 128mb to X800 XT 256mb? Any of you seen benchmark that includes the above two cards?
