I put this together with the help of members from the PCPartPicker forum. However, I wanted to get the opinion of the TH crowd. Could I play games at 4K with this setup? Will it run too hot or make too much noise to be enjoyable? Will I get smooth framerates on the most graphics-intensive games? I didn't include case fans because the case I chose already includes two that add up to ~134 CFM airflow, and I figured that would be enough. PCPartPicker estimated the wattage at 1119 W, so I tried to play it safe by getting a PSU rated at well above that.

Noctua Fans are pretty much the go-to brand for silence. I've found Corsair's fans to be just fine though. Noctua has released fans that use black instead if their brown-scheme. So those might be a better choice. Three 120mm is what I would go with. But if noise is an issue two 140s would work fine. I would put the bottom fan in, and make...

Hey, I'm new to this. I have no idea what is sufficient for smooth 4K gaming. You want to maybe enlighten me a little, or are you satisfied with just being condescending?

I'm satisfied with being condescending. You're listing 3 of the top tier GPU'S for a 3-way sli and you're concerned about 4k gaming? In short yes you'll be able to play 4k if fact you'll be able to play anything and everything on 4k.

Sorry for the delay...

This rig is great for 4k gaming, I'll do a break down in case you would like extra information

i7-4790k is a great processor, especially for a high-end built with Crossfire/SLI.
I'm personally not a fan of Gigabyte's motherboards, but that is more personal preference on my side.
Ram is decent ram.
I don't know much about Toshiba's HDDs so can't help you much here.
R9 290X 3-way Crossfire is excellent for 4k gaming. Better, in my opinion, than 3-way GTX 780 Ti SLI. This is do to what I've seen, and that is AMD cards perform better at higher-res applications.
Case is decent.
Sufficient PSU.
Recent OS.
You will likely want to fill your case with as many fans as possible. This is because the R9 290x runs hotter than your average card. It can handle the heat a bit better though. Make sure the top/back fans are blowing out, while the side/front/bottom fans are blowing in.
Since 4k is so new, some games may have issues at that resolution. If any rig is going to run the new games, it will be this one. So enjoy the 4X 1080p awesomeness!

If you have any questions or concerns, you know where to ask!
Note: Crossfire is AMDs equivalent to Nvidia's SLI.

Thanks for the assessment! Regarding the thermal situation: the case already includes front and back fans, but I have room for another 120mm fan on the bottom and either three 120mm's or two 140mm's at the top. Which option for the top is better, and do you have any recommendations as to the fans I'd use to fill these spaces? I'd want something that's effective, but quiet.

Thanks so much for all your help! However, I have one last question. I was wondering about overclocking: Is there a site that has general guidelines on what the maximum "safe" overclock is, for each individual component? I would like to get as much out of the computer as I can while still being 99.9% sure that it won't die from being overworked.

I'm not much of an overclocker, so I don't know what the best resources are and such. After a quick search I found-

If these aren't at all helpful I can ask some OCers I know.

The overclocking on the 4790k isn't as great as it was made out to be unfortunately, and it ultimately depends upon the chip itself. (some get lucky, some don't) I've been able to keep mine at 4.7Ghz stable at 1.275 volts.

Okay, I'm getting four 120mm fans to fill out the remaining spaces in my case. I settled on the Noctua NF-S12B redux-1200, because of its low noise level. Each one moves 59.1 CFM of air. Will that be enough to keep everything cool, along with the case's stock fans?

It should do fine. This is really a precaution, as the R9 290x runs hot, and you will have 3 of them in close-quarters. 4 Noctua fans + the stock fans should do just fine. Enjoy the awesomeness of 4k gaming.

I'm going to sit back here... totally not jealous or anything...

Hey, hold the jealousy until I can actually afford to buy it. ;) I'm just laying a blueprint so I know how much to save. At least it's cheaper than the build in my other topic.

I need atleast 5000fps to get my drop-shot 360 no-scopes on sheep and piggies.
Anyways, off topic. If you have any more questions feel free to ask.
