Does that mean that this has got something to do with a CPU limit? I thought I had at least raised it a considerable amount because of using a 3970X at 5GHz and Metro Last Light has a good usage of many threads.

Few games take of full advantage of the extra cores and threads of higher end pc's. Generally, 4.0-4.5 is good enough for up to three cards. I do recommed 4.5+ for three of the newer cards and for quads. At your speed, its not a bottle neck. You can always run synthetic benchmarks like 3DMark (11 and FS). Open up Afterburner, detach the monitor cell and expand it (make sure it shows at least all of your gpu's usage, and recommended clocks). Run the test, if you're noticing the cards are not hitting 99% in the gpu tests, then you may have something holding them back. But I doubt there's a bottleneck with your cpu @ 5.0.

Also, as the resolutions increase, the workload really starts to hammer on the gpu's and less on the cpu. I'm currently running 4.7 with no issues at all.


As far as the cpu, four cores with eight threads seems to be the sweet spot. Some minor exceptions will have a slight advantage with more cores/threads but the differences is hardly. I went from a 4c/4t cpu to a 4c/8t cpu and immediately noticed a good difference in a few games like BF3. But didn't see any advantage when I had my 3930K (and hence one reason I sold it). I actually came out less then a fps slower in the Metro LL bench (5760x1080, highest settings, cpu's @ 5.0, 2700K vs 3930K, both using tri-sli GTX 780 stock clocks). So, unless you have other applications that require more cores/threads, right now, there's really not much benefit in gaming. And yes, there's the argument the new consoles will change this, but by the time that happens, our current cpu's will be a bit dated and will have newer options then. 6c/12t will eventually become the 4c/8t standard imho in the next few years if we continue to evolve down this path.

Thank you for your detailed answer. Well, and I want to buy a 5960X with 8 cores next! What will that mean for games, hahaha. But seriously though, I have actually thought about if it would not have a worse performance for games than a 3970X. The "problem" is, I would like to pre-order it, so I can probably not really look at benchmarks before that.

P.S. Mayne, you got lucky with the waterblocks for your Lightnings. I had to RMA all four of my graphics cards (also from MSI) and they offered me Lightnings, but I had to refuse that offer because I could not find enough waterblocks for Lightnings anymore.

I'm about to get a new card (second hand, and temporary solution) so I was thinking.. HD 7950 Crossfire seems the way to go (they go for cheap apparently) , however I'm only skeptical about microstuttering, it seems to mainly happen in a few games, but I was curious if some people here could give me some feedback before I make the final decision biggrin.gif.

Well, definitely understandable. The newest gear makes anyone giddy with excitement. I have to constantly remind myself of the meager gains vs the extra cost to upgrade and that's enough to restrain my itchy fingers to upgrade (redface.gif).


I got my Lightnings in a trade. The seller had four with blocks and was interested in moving to GK110. I had three 780s and the thought of running five monitors was too good to pass up with the Lightnings. These lightnings are fantastic. Though I had to rma two of them, MSI has been very good and got me on the latest BE v2. i sold the other two PEs to buy two more BEs. What a mess that turned out to be but I did find a good seller to finish this, ahem, "upgrade" tongue.gif. They're doing pretty good pushing through five monitors and though its tempting going with two 295x2, I can't afford that right now. Plus, this build is just a few months old so might as well squeeze as much fun as possible. I only game so I have no other concerns with other applications for my rig. Watching anime online is no sweat tongue.gif.
