I currently have my old build from back in 08 and have decided to upgrade my graphics card(GTX 280). I'm looking at the GTX 770 right now and I'm wondering how much of a bottleneck will my CPU be: QX 9650 @ 3.0Ghz. I know it will be a bottleneck but will it be so bad that I won't even get an improvement from my GTX 280?
