What CPU would you guys recommend for 4 R9 290X's (each with 8GB of video RAM)?

I am not sure what CPU to get in order for it not to bottleneck the GPU's. I was thinking of a 4790k or a 5820k. Do you guys think I should get the 5820k over the 4790k, stick with the 4790k or get an even better processor than those two I have listed?

An i7 will not bottleneck NOTHING... it's a beast. There will be not much difference between 5820k and 4790k, if you have money go for the 5820k.

(Just curious, which CPU would you get better than an i7? Is there any CPU better than that?)

You could even run an i5 4690K without any problems...this bottlenecking propaganda nonsense has well and truly gotten out of hand. People seem to think anything other than an i7 will throttle their gpu.

If you want to go big, go for one of the 2 cards you mention, perhaps the 5820 as it is x99 and designed for nuts systems like Quad crossfire.

You can also wait till September for Skylake i7-6700K

Sorry I was quite vague in my first answer, I didn't necessarily mean to say the 5960x is what you want because the price tag is insane, but my point was I'm not sure if a 4 way crossfire with one of the best amd cards would be the way to go, but of course if there is no bottleneck then go for it because it sounds like it would be an amazing machine!!

And the CPU is a bottleneck...what complete and utter garbage hahahahaha

Where do we get these people from!?

Rather than listen to some youtube amateur you want to properly read into how these components work together and discover what bottlenecking actually is.

This is getting super annoying

If the best CPU (i7) does bottleneck a GPU, then what CPU you need? an i9999 with 800 cores at 75GHz? Lol.

People here on Tom's Hardware always seems to need the best tech and even with that they are never happy. Until two months ago I still was using a core2duo with shitty nVidia 210 and was working well two months ago.

Well I meant maybe I could get a better i7 for example the 5960x but it is a lot of money so if a lower i7 CPU wouldn't bottleneck the GPU's then I'd be happy to go for it

Any i7 is a beast, so dont worry and go with the 4790k and dont listen to these perfectists.

Please STOP saying the word bottleneck when referring to an i7 4790K or higher!!!!!!!!! STOP!

I EXORCISE YOU OF YOUR DEMONS! LEAVE HIM BE LUCIFER! RETURN HIS SOUL!

There...now you should be ok and not believe this utter bullshit that such high end CPUs will cause any problems for you.

My recommendation remains the 5820 due to the socket and hardware available in terms of x99 chipset etc. It sounds like the right fit.

And for heaven's sake...this isn't an insult, however you seem to know a limited amount about any of these CPU's. The extreme edition would be wasted on you as you wouldn't know how to use it properly and appreciate what it was made for.

The models you mention before are right for your system and needs.

No problem, it's a dense market out there and it is easy to get sidetracked by propaganda and false information.

Buy any of the i7 you mention safe in the knowledge they will perform SUPERBLY

OK thank you yes I don't know much about CPUs that's why I asked for your people's opinion and sorry for using the term bottleneck it's just a term that seems to be going around people like me who don't know shit about computers :) Thanks for your help again :)

For running four R9-290Xs in quad-CF, you will need an i7-5930k. That CPU will support 40 PCI-E lanes and that will be enough to run the GPUs in x8/x8/x8/x8 mode. You will also need an X99 motherboard which supports 4-way SLI / CF, such as an ASUS Rampage V Extreme. The 5820k will not be enough due to only 28 PCI-E lanes and the 4790k will definitely bottleneck due to 16 PCI-E lanes. Hope this clears up your inquiry.

Thank you for your input. Would any AMD CPU's work, for example the best one being FX-9590 (which is a hell of a lot cheaper than the 5930k :))?

I'm still trying to think of a situation that requires 4-way CrossFireX and 8GB VRAM on each GPU: 9 monitors running a combined 11520x6480 display resolution?

As for the term "bottleneck", it has a negative connotation to it. However, its real meaning is what the limiting factor is in the graphics being displayed on your monitor. Now, if you have 4 R9 290Xs rocking 8GB of VRAM apiece, then it is possible that you can run into a situation where the CPU (even the beastly i7-4790K and i7-5820K) simply cannot keep up with the GPUs' needs...in which case, the CPU is technically "throttling" or "bottlenecking" the GPUs' full potential. Doesn't mean it's a bad CPU, just means you may want to rethink your graphical setup.

As for AMD CPUs, you don't need the FX-9xxx series. An FX-8320 has more than enough PCie lanes to run quad CrossFireX at x8 speed, & if you need extra juice it can easily be OC'd with the right board.

Thanks for your input :) It's great that an AMD processor can deal with my specifications as I can reduce the price that I'd have to pay for the costly Intel CPU's, namely the 4790k or the 5820k. As for the 4 R9 290x's, I know it is a LOT of graphics cards and power, but I've done some research and for what I need them, which is playing GTA 5 on 4k screen with everything on absolute ultra settings, including for example MSAA on 8x and managing to keep the fps at 60 or above is quite a challenge for most GPU setups, but this setup will do just fine. Here is a link on where it shows the game tested at similar settings at the end on several different graphics cards: http://kotaku.com/grand-theft-auto-v-benchmarked-pushing-pc-graphics-to-1698670906

The FX-9590 is an overclocked FX-8350, which was AMD's cheap way of trying to match the i7-3770k in performance. It's single-core performance still falls well short of the i7-5930k and that's where potential bottlenecks could occur. Overall, the i7-5930k can cope with quad 290Xs much better than the FX-9590 can with lower power consumption and heat.

Fair enough but what is the next best CPU which could handle the GPU's fairly well for a cheaper price?

Some bottlenecks may occur with this, but it's the next best thing since this CPU also supports 40 PCI-E lanes.

Are the high-end motherboard and CPU cooler really necessary or can I get cheaper ones?
