I have a Dell precision T3500 with Xeon W3530 Processor running at stock speed 2.8 ghz Max in turbo mode 3.06 ghz .. and 8 gb of ddr3 ram @ 1.066 mhz and an AMD Firepro V8800 gpu .. So I wanna to upgrade the gpu for a gaming one and I'm thinking of buying a GTX 960 2GB but I wonder if my cpu will bottleneck the gpu .. What do you think ?
