My G13 gamepad has a CPU/mem monitor that i glance at occasionally, sometimes 1 or 2 cores spike to near 100% but mostly its 40-60% or so (in Rift for example). But that doesn't mean I won't benefit from the cpu/mobo upgrade right?
Where did you guys see any comparison between the 2x 4890s and a single 570/580? I can't find any direct comparison worthwhile maybe my google-fu is weak i dunno. Since 4890s are dx10 and 570/580 dx11 most charts i see don't show the two side by side. I saw some single vs single but not cf 4890 vs single 570/580.
