Hello, What I want to ask as well is, will a GTX 770 Bottleneck with a single 2009 2.66GHz Xeon processor? The reason why I am asking this, is because it may be better off getting a 760 over the 770 if the 770 is going to bottleneck. It would be a waste to get the 770 if it were to bottleneck because I could get the 760 cheaper, and run on less power. What do you think is my best option? My specs: 2.66GHz Xeon GT120 10GB of Memory 640GB HD 1TB HD (Will be adding an extra 1TB HD) (Possible SSD in the future) Thanks for any help!
