I am helping a friend upgrading a pre-built Dell Inspiron with an i5-650. He wants to upgrade the GPU which in turn will make a PSU upgrade necessary. Will it bottleneck an EVGA GTX 660 FTW Sig2?
The computer with its current graphics card seems to handle The War Z fine but at Low settings, so I am not sure on whether it is the GPU or CPU. The i5 is a dual core.
