I am going to buy a geforce gtx 660 ti graphics card, i am using a amd 245 ii x2 proccessor and i have been told this would cause bottlenecking of my graphics card, if i were to upgrade to the AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor would bottlenecking still be a concern?
