I'm upgrading from a 9800GTX to a HD4890. I normally play on a resolution of 1440x900. My CPU is Q9300 at default settings. PSU is 650w earthwatts. I play mostly FPS games such as COD4, Crysis, etc. My question is if the HD4890 would be the best fit with my CPU (don't want a bottleneck), and if so/not, do you have any other reccomendations without spending like 200 bucks.
