i7 4770k with liquid cooling + 4 way GTX 780 SLI

Hey I was wondering what should I over clock my cpu (i7 4770k @ 3.5GHz) so it will not bottleneck 1 GTX 780. Then what should it be if I ran 4 way SLI GTX 780's. The mother board I'm using is ASUS Maximus VI Extreme Motherboard. The CPU cooler I'm using is a Corsair Hydro Series H80i CPU Cooler. Have a 1350w PSU, 16GB 1600MHz of DDR3 RAM, and a 10,000 RPM Velocirapter HDD (450GB). Any information would be greatly appreciated :)

It will not bottleneck one or two at stock speeds. It will bottleneck 4 that's for sure. I'd OC to at least 4.5Ghz. an i7 extreme bottlenecked 4 titans at 5Ghz. It will bottleneck but a lot less.

Thanks for that, you think the CPU will be stable at 4.5GHz with that cooler I mentioned? (haven't actually bought this system yet but going to this week probably).

I'd get the H100i instead, it's better. But what's your budget? I could put together a build for you if you want!

It's not a matter of budget so much, it's more of a hobby machine. At the moment it's going to be a add on things as I go kind of build. I might get the H100 since it's only $16 more. My first post on this thread is what I initially want to start out with, but end up running more ram at higher frequency, and 4 way 780's. Another question I have is what would a decent cooler be for 4 way ASUS GeForce GTX 780 DirectCU II OC 3GB. Preferably a dedicated multi GPU cooler. It's on the motherboard I posted earlier and it will be inside this case: Aerocool X-Predator Case Black Edition (is that case even appropriate, will it require something better than this case?).

Well with the amount you're spending on GPUs I recommend going with a 6 core SB-E or waiting for IB-E, the i7-3930k or 4930k. I also recommend a custom liquid cooling loop for your CPU and GPUs.

Yeah I was just checking out about the 4930k, looks like it's estimated to arrive in september sometime, so I might just wait for that. I'm not that familiar with liquid cooling when it comes to GPU's as this will be my first time using SLI as well as liquid cooling.

I just read that the 780's are only supported up to 3 way SLI. Only the Titans can go 4 way, as well as other lower end GPU's. I've changed my mind in that case, for now I might just run 2 way. Would this require advanced cooling or would fans be fine for just 2 (remember the cpu will be liquid cooled still).

That's true, just checked. You could always go 3-way or you could go 4 way CF with the radeon 7970 if you want to do that. But since you're waiting for the IB-E I suggest waiting a little more. The radeon 9970 will be out in October to rival the 780. It is supposed to be cheaper and perform better. It will also support 4 way CF. I'd wait for that. To answer your question though, you should be fine with the stock coolers on the 780s.

Edit: you could also go 4 way SLI with the 770s if you want, but I'd still wait for the 9970.

Not a big fan of crossfire with AMD these days, the SLI technology seems to have less issues (based on a lot of reviews I have read). I think I'm just going to stick with the cpu H100i cooler and have 2 780's use their stock fans. How would 3 780's run on stock fans in that motherboard and case since I'll make sure there is plenty of airflow (also the room I'm in is cool, the AC vent goes straight on the tower).

I know but CF is getting better. Its basically fixed for single monitor and more then 2 GPUs reduce microstutter a lot. The 9xxx series is also supposed to be a very major upgrade. I recommend waiting. As for the 3 way SLI, I recommend custom cooling, but it'll probably run OK.

Thanks a lot for your help mate, just got one last question that case I linked you before, will that be ok for my components? Space and airflow wise (I want to install the cpu's radiator above the case intaking the outside air)?

Your case should be fine :)

Cool thanks for all your help mate, I figured if I'm gonna spend this much money on a new system, gotta make sure it'll all work well and run like a beast :p
