Planning to upgrade my rig for the new wave of games coming out. I am definitely going Nvidia 570 or 580. What I am wondering, is should I upgrade the CPU & motherboard as well, or will my current rig be enough to get the most out the card and the new games.
Phenom II X4 945 OCed to 3.8GHz
4 gigs RAM
2x HD 4890s in crossfire
MSI 790GX chipset motherboard
I am debating upgrading to an LGA 1155 system, new mobo and i5 2500K (I'd OC it of course). Like I said the graphics are definitely getting upgraded, and my question for the forums is will I see a noticeable difference if I upgrade the CPU & mobo alongside the new graphics card, or will the upgrade be so slight I should invest that into other parts (a nice SSD, 2x 570 for SLI, etc)? I only worry about some weird issue with the 790GX chipset or the current Phenom CPU not fully utilizing the 570/580, could that pose any issue?
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.
