Currently running the spec in sig, monitor is an old 60Hz benq fp241w, currently using a single gtx 670 wf clocked at +130 core, +770 memory. It copes very well in what im playing, mainly bf3 and bfbc2. Im thinking off eventually adding a second wf 670 and upgrading to a 120Hz monitor. Im wondering if the cpu will make much of a bottleneck with this setup. Cpu is currently only at 4.2ghz, but i intend to clock it higher.
