Currently running Gigabyte 965P-S3 mobo, Core2 E6300, 2G GSkill DDR2-800, GeForce 8800 GT. I want to upgrade so that I can run most anything on a Dell 2405 FDW monitor. Budget is 1,000 or lower. I don't want rock bottom, but I don't want to spend more than I have to. I've not paid much attention to hardware of late and not sure where to begin.
