So I had some free time and a GTX670 available so I decided to check out how much CPU frequency actually mattered at my resolution [2560x1440]. After doing some tests I realized I could actually share the results since the 670 is actually a really common GPU with nice price/perf and with the Korean monitors becoming more and more common the setup I had is suddenly a pretty common one.
Thank you, I have a similar system except I'm under SLI GTX680. CPU @ 4.5Ghz to 4.6Ghz is the sweet spot for performance per watt. Gaining over 4.8Ghz actually doesn't benefits much anymore except for 3D Rendering / Bench (Maya, 3D Max).

Yeah that would be my conclusion as well. Pushing the CPU over 5ghz give you more epeen, is more fun is and is beneficial with F@H so I'll keep mine chugging at a higher frequency.
And I really wish I had a second one to test with, would be interesting to see the results.
Less noticeable at high resolutions and more noticeable with SLI. Not that I have any experience of SLI setups with the 600 series, I'd still imagine that they're just as CPU hungry as the 500 series if not more. 580SLI and tri SLI setups for example saw pretty huge benefits from SB.
Also weird to see a post here, just stumbled on my thread again at random
Starcraft II and synthetic benchmarks appear to be the only applications with a palpable difference from CPU overclocking. Not sure how that translates into what percent of games will be sensitive to overclocking, but my guess MMOs would be, and any games with lots of physics and multiple units to keep track of with lots of configurations (such as Starcraft 2).
Nice test. Really good to see and some interesting results. The gain over 5GHZ seems non existent or not even a gain but a disadvantage. I hope I can get my 3820 at about 5,2 just for the epeen hahaha and then get it down to 4,9 for 24/7 or max memory bandwith depending on the ram capabilities.
Really should test some MMOs or games with high intense physics built into them. Planetside 2 really benefits from clock to clock performance on the CPU, also starcraft and WOW might be a good choice too. overall good results, kinda makes me satisfied with my 4.9ghz on my 2500k right now, seeing the difference between 5ghz and 4.9ghz isn't too significant...
Yeah thanks for posting......Kind of highlights the need for a balanced system....no point in the majority of cases in ocing the crap out of your cpu if your running more mid range graphics.
What would be nice to see is how this would pan out if you were running one or two high end gpu's that were oc'ed to the limit.....just how many GHz on the cpu are required to feed say 2x heavily oc'ed 780's......interesting stuff
