Hello, I'm currently running an i7 920 @ 4Ghz and I'm running into some serious bottleneck issues with my 2 GTX 770s. I can only get about 66% GPU utilization at most. If I drop my OC down to the stock 2.66GHz, my GPUs won't even get above 800 mhz (stock is 1101, turbo 1215). So my question is, should I go ahead and start working on upgrading (I'm thinking X99 with an i7 5820K) or should I wait to see what is in store with NVLINK? From what I'm reading, it looks like there's a pretty solid chance that NVLINK won't be coming to x86-x64 processors anytime soon due to what I imagine would be Intel and AMD's reluctance to support it on their processors. What do you guys think?

My only problem with an i7 5820 is that it only has 28 PCI-E lanes. I recommend you look over all of the compatible CPUs (to include Xeons) posted here for the X99 EVGA motherboard you want and see if you can find a CPU that might give you a bit more performance if it is within your budget: http://www.evga.com/support/motherboard/

28 lanes are not so good as 40. But better than 16 as i7-4790K. Anyway some motherboard as X99 Sabertooth have everything you need even for i7-5820K. On your place I would go now on X99. i7-5820K have normal price because 28 lanes. Intel for such money usually offer 4 cores. Better 6 cores and 28 lanes than 4 cores and 40 lanes... I mean for me is better.

You sure your cards aren't being throttled due to heat? I ran an almost identical setup, and had full gpu utilization.

I also felt some bottleneck on my old i7 950 stock X58 system with my 780 Classified. I believe you start seeing some from GTX 680+ and adding more than 1 GPU will just exasperate the situation.

Yeah, definitely not being bottlenecked due to heat. I think the highest I've ever seen my cards get outside of furmark is like 75 degrees and I'm constantly looking at it in the G15 applet.
Thanks for the heads up on the 40 lanes. I definitely didn't know about that. I think 28 lanes will be enough, although it is a bummer. I doubt I'll ever use more than 2 cards which I think 28 lanes should suffice without a noticeable performance hit. But I'll definitely look at some of the Xeons and make a decision. Thanks, guys!

My 930 + 2x 680s had that problem. I could not get full usage, also on GPU only benches I got noticeable gains form OCing the CPU, the X58 was an AWESOME chipset and great processors form back in the day, and honestly in a lot of areas are still really great for a lot of things, but if you are kicking the crap out of the CPU or are using some heavy duty cards in SLI you start seeing that you are running into a platform bottleneck, which is unfortunate, those X58 boards were really great.

Although, I think I should mention that there are a lot of games that I do get full GPU utilization out of. But the newer games, such as Dying Light, Witcher 3, Ark.. I might get to 80% in a cutscene but 50-66% would probably be average.

Yeah, I was blown away with my setup back when I got it in 09. I couldn't believe I got 4ghz on air! I know I'll definitely benefit from an upgrade, though. My SSD will enjoy the SATA 3, a few USB devices will enjoy the USB 3.0, and I'll get a huge bump in GPU performance. Time to do some shopping....

I still love my X58 system. Technically I have two but have one as my backup/Folding rig in the other room. Till this day they are still great. Honestly, I didn't feel a huge improvement I expected in certain areas on the X99 platform unless you use M.2 and or mutli GPU in a surround setting other than doing work like renders and the likes or benchmarks.

I'm in the same boat as you, on an i7 920 @ 3.8GHz and planning on upgrading. Honestly the X series of chipsets just seem to last longer before having to upgrade. So I'm thinking of upgrading to X99 but kind of waiting to see just how Skylake compares, and the fact that Skylake is going to have 20 PCIE lanes means that the 5820K for probably still roughly $50-$60 more will have 8 extra lanes, not much of a lane boost, but 6 cores > 4.

i was running a 920 @ 4.2Ghz w/780 in SLI(same bottleneck issues) i made the upgrade to x99 classified with a 5820K @ 4.55Ghz w/ 980ti in SLI the 28 lanes are fine for my gaming needs and for 250 more you can get a 5930K and not have that concern. it really is night and day coming from a 920, i would pull the trigger. i feel the x99 chipset is of the same caliber of the x58 chipset and will last another 6-7 years without any need to upgrade anything buy video card. gtxjackbauer Honestly, I didn't feel a huge improvement I expected in certain areas on the X99 platform unless you use M.2 and or mutli GPU in a surround setting other than doing work like renders and the likes or benchmarks.
i agree with this on a single card it didn't bottleneck, but back when i had 570s in SLI i started to notice the bottleneck and then really noticed it with 780 SLI. While the speed M.2 is very intriguing, real world performance was still in line with my SSD. So, if the plan is to run SLI x99 @ 1440p/1600p+ and not worry about upgrading an entire system down the road this would be a good choice.

I just posted in another thread, so I will keep this one extremely short. All of the NVidia Pascal articles all refer to the Processors for "Deep Learning" which is not gaming performance. This applies to all parts of Pascal including NVLink. Current "Deep Learning" GPUs are the Tesla series, and they have been running 8 of them for processing, and they are not Pascal Based. Don't base your gaming ideas on this Deep learning thing, because you don't see anyone stuffing 4-way Tesla cards in their computer for gaming. The NVidia articles I have been able to find all include the performance of the deep learning application of Pascal, so we may not get the gaming performance that people reading those articles are expecting. Notice that the 980ti isn't displayed as a Deep Learning GPU, but instead it is a Gaming GPU. Just some food for thought.

I can't wait to see ASUS Maximus 8 Impact and EVGA Z170 Stinger... Mainstream platform now is best to build in small rigs as EVGA Hadron. They will work and with DDR3 and with DDR4. E-ATX build is better for X99. Only owners of i7-4790K have really no reason to update platform on Z170 except if they want to PCI-E 3.0 chipset and DDR4. I will build X99 and that platform will stay with me 5 years 100%, but for 3-4 years maybe I build one small rig with newer features. X99 will stay as 24/7 working platform. Today I read specification for E5-4669 V3... My god. 18 core Intel, 7000$... I didn't found board for supporting such processor with single socket... maybe X99 WS IPMI, X99 E WS and similar.

I was about to invest in X99 when I heard about Skylake. Need to wait & see whats coming. I am debating between Z97 vs Z170. Lets see how the 4790k vs 6700k battle comes to and end.

You should look for some much better option. Intel 5820K + EVGA X99 Micro 2 + GSkill 3000MHz DDR4 now is capable to build for 680$. Even 630-650$ maybe if you want 2666 or 2800MHz DDR4 4x4GB. Such situation should be used because owner of X99 no way to need upgrade because performance next 3-4 years. All new technology are implement, USB 3.1, M.2 Ultra Speed up to 32Gb/s... That's almost half price of some Intel Xtreme platforms but you have absolutely same options. I agree Z170 is interesting but with i7 and Stinger example... But again Z170 you can't pay less than 600$ for i7 + Stinger and 2x8GB DDR4 or DDR3 now is almost same. Even more than 600-650$. I would not miss Intel 6 core for 300$ and later i7-6700K will cost minimum 380$, people expect more.
