I currently run SLI 560s, and my 1100T was significantly bottlenecking them in CPU intensive games. Unfortunately, while the 8350 shows better performance/less bottlenecking, it hasn't NEARLY solved the problem.
What's worse, in fact, is that both of these CPU will bottleneck a ***SINGLE*** gtx560 when playing games like WOW, FF14, GW2, etc. Basically any game that prioritizes a single thread. And by bottleneck. I'm talking about dropping from 100+ FPS in single group situations (with 97%+ GPU usage) to literally an UNPLAYABLE 20-25 FPS in large-scenario battles (such as GW2 RVR). These results are the same regardless of gameplay settings, and/or running with a single card or running in SLI.
I'm wondering if this is a good time to build an Intel rig, or if I should wait a few months til the summer/fall. Is the 4820k or the 4770k setup a better buy for mainly gaming?
