Actually it can. Its been proven i5's can be a bottleneck, you need a high OC in some games or a i7.

660ti is a tad suspicious but not impossible.

This.

Also, WoW is kind of a freak of nature. The game has been going on for so long that they have had to hack major updates into the engine several times over the years to try to stay up to date. At this point, I would chalk it up to a software issue, I seriously doubt that WoW is proving too much for a 3570k. More likely, your setup is just too much for poor old warcrack, and the game is what is doing the bottle-necking.

Proof please?

There's no way in hell a 3570k can't run both 660's 100%

I didn't say 660ti did I? I said it can be a bottleneck(speaking of other cards) so it is possible here in this scenario considering WoW is CPU bound.

P.S. nice OC on that sandy, im jelly.

I was reading this at work today. Great conversation with some great evidence where a gamer experienced a bottleneck in BF3 multiplayer between his heavily overclocked 3770K and GTX 670s in SLI.

TLDR: Only higher clock speed somewhat alleviated the problem, and even then he couldn't sustain 60 FPS in BF3 multiplayer. Not even upgrading to an i7 3930K helped, but his research showed that there was a benefit when going from a 4 thread processor to 8.

I understand that BF3 is much more taxing than WoW, but his gear was also much better than mine. I also conducted some of my own quick benchmarks with FRAPS in WoW going from Paw'don Village to the lake and back to the portal to Stormwind:

Stock (3.6GHz turbo) with SLI:

Frames 4363
Time (ms) 69125
Min 48
Max 80
Avg 63.118

Overclocked to 4.2GHz with SLI:

Frames 4642
Time (ms) 67266
Min 56
Max 86
Avg 69.01

Some quick ~1 minute runs, and already expected results. 3.6GHz to 4.2GHz is ~16.7% overclock, and I have exactly that as an improvement in minimum frames. Coincidence?

EDIT: Correction. Gamer in the forum I linked was playing with an overclocked i7 2600K and GTX 670 SLI.

I dont know about WOW but I'm suprised by his findings in BF3. My friend at work has a 3820 w/ SLI 680s and he says he never goes below 60. Also my friend with a 2500K at 4.7 w/ SLI 670s says the same. I would think a 3930K overclocked would crush BF3.

With my I5 I can sustain FPS at around 70. This is in 64 Player Gulf of Oman and Caspian Border. So I am CPU bound after 70 or so. Lowering mesh detail will give you more frames. This is the only setting that seems to have an effect on alleviating CPU spikes when all hell is breaking loose. I usually just cap my framerate at 60 in 64 player maps seems to give the most smoothness. This will give me two completely flat lines with the perfoverlayvisible command.

I also think my I5 is CPU bound in Crysis 3. My frames will drop to 40 while my Titan is only working at 50%. This usually happens around areas with tons of grass. Lowering object detail helps this out.

What you are showing there does appear to be a CPU bottleneck to me. Did you try going to 1 card to make sure you aren't having some weird negative scaling issue in WOW? I dont think an I7 will help with that particular game though. Does WOW even use all 4 cores of your I5?

I know my next chip will be an I7 or a hexcore. I think going forward more games are going to to start needing them if you want 60+ FPS.

Dude!

Run this and compare to the BUNCH of other guy´s systems.
http://www.overclock.net/t/1360884/official-top-30-unigine-valley-benchmark-1-0-fill-the-form
Also do more investigation with other benchmarks like 3DMark / Vantage / Heaven
with the similar / same Hardware.

I have also two 660ti and much experience with it..
look, the point is.. yiu wont get a "classical" bneck with that combination of hardware.
You (we) might have a small disadvantage compared to 8mb or 12mb(!) cache, but nothing
that should make you regret that you´ve chosen this CPU!

I also play Battlefield 3 on ULTRA and do not have the issues you described, even with
forced downsampling @higher resolutions than 1080p.

My system begins struggling with higher Resolutions then 3000 x 2000ish
or 26xxx X 16xx combined with high supersampling / AA and this is mainly
due my Vram..

The magic is to find the right settings for the Nvidia settings / NVidia Inspector
..for the right SLI settings and even OC settings for GPU and CPU.

Also there are always guys customising the SLI-Bits that might also change
your explerience for the SLI- Scaling

i honestly hope this brings some light into your problem
post #18 of 18
like the other guys said, just disable SLI for WoW. that's what i do too in NFS Shift 2 Unleashed that is not optimal for SLI.
