Hello. This is my current computer. AMD 965 @3.8GHz (slight OC) Cooler Master V8 2x4GB GSkill ARES 1600 Gigabyte GA-MA790FXT-UD5P Corsair 650TX Cooler Master HAFXB Crucial M4 Benq 1920x1080 Gigabyte GTX 460 OC 1GB I was wondering what is the best graphic card to put in that pc without bottleneck. Does a 460 SLI worth it? Thanks.
