Will the Intel Core i5-4690k(Devils Canyon) bottlekneck GPU performance with 2 290x's or 2 290's in Crossfire?

post #1 of 11
Thread Starter 
I was originally going to buy the Core i7-4790k For my upcoming build, because I wanted to be extra sure there was no one component not being able to keep up with another components('s) such as dual r9 290's or dual 290x's.

I was wondering if this setup(Specifications Below) would be fine for running dual 290's/290x's

CPU: Intel Core i5-4690k (URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16819117372)

Memory/RAM: 16GB(4x4GB) DDR3 @ 2133MHz @ 1.5v (URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231503)

PCIe SSD(OS+Storage): ASUS ROG RAIDR 240GB PCIe 3.0 x2 MLC SSD (URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16820785002)

GPU's(x2)= ASUS DirectCU II R9 290X's or SAPPHIRE VAPOR-X R9 290's(x2)

R9 290X GPU URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121840

R9 290 GPU URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202103

Power Supply/PSU: Corsair HX 750W PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010

Those are the main spec's.

I also want to know if the corsair HX750w can handle this setup and/or if I need to get an HX850W

Also I wanted to figure out as far as power goes if I could do this setup w/ 2 cards and the Core i7-4790k

Anybody's help is appreciated smile.gif

There's really no reason to get a 290X when the GTX 970 is faster and cheaper, and the regular 290 is just as fast and much cheaper.

If you're going for 2x290s, I'd go for an 850W PSU at the very least. There are probably better PSUs for the money. Be sure to check out this thread.

The ROG SSD isn't good for the money, no Sandforce RAID SSD is. If you MUST have a PCIe SSD, I suggest this plextor one.

The 4690k is fine, the 4790k would only be slightly faster in a handful of games.


What motherboard/heatsink do you plan on getting?

EVGA SuperNova G2 are better and cheaper then the Corsair HX units so dont bother you are getting less and you will be paying more.

With mantle or directx12 there wont be but at directx11 at 1920x1080 in some games could

Check pcartpicker for the prices of the 290 pcs+ whuch is the 290 with best cooling or if you dont care the tenperature there are 300usd r9. 290x from xfx with a free mousepad for 303usd if cannot support the temps of the 290/x`s then get 970s gtx in sli but they are 330usd minimum


For the psu check pcpartpicker and look the rosewill capstone 1000( rebadged superflower green) if kot the evga supernova g1/g2 1000w

The 4690k is cool and doesn't afraid of anything, it won't bottleneck your 290's, but you should get two 970's because.. well, they're better and cheaper. No reason to stick with AMD.

I've heard recently, a few months after i posted this that the gtx 970 had issues properly utilising and accessing about 500mb to 750mb (depending on scenario/game ) of its memory, I know they are releasing/ have released a driver update to fix it, but the fact that that it had an issue like that makes me question its general reliability, and without a doubt, the 970 is a wicked FAST card, in gpu intensive, higher graphics settings situations, which is what most people worry about. but these cards im going to pick are going to be a build im spending $2500+ on, and i'm not going to have money to build a new rig, or buy 2 new cards after the fact, I plan on building this, then upgrading(gradually) and replacing parts as needed, so Its more about future proofing for me. I really want SLI/CFX, but the 980 seems to be just a great option, top-end, I havn't heard (that i know of) anything bad about it, bugs or performance wise. Its not a kind of card I'd EVER  SLI, I just don't need that kind of horsepower, even if i get x2/x3 1440p or 1080p(Widescreen) monitors.

 

The 290's , 290x's ARE aging, and I doubt they will be my pick, they are just too outdated, yes they have massive amounts of memory(Up to 8GB, LOL), and GIANT bus widths (512 Bit) - thats only useful if you plan on running multiple/two ultra high resolution (4k, or 2k wide screen stuff like that) monitors and you need a massive frame buffer. But then again, thats just the so to speak "Storage" of the actual output computed by the GPU, if the GPU is outdated, and much slower than that then its just counter-intuitive. I dont understand that, it doesn't take an EE, Or a Computer Engineer, Embeeded Sys. EE to know that if you have a massive frame buffer and bus width, you HAVE to scale it (and sometimes, you have to reduce it to keep everything balanced!) to the compute speed of the GPU. AMD seems to have the idea that "MOAR IS BETTERRRRR"; 6/8 Core CPU's with arguably AWESOME multi-threaded performance, but how many games or applications as of now are truly well optimized for multi-threaded CPU's? Gamer wise, not a very good idea, if your not on a budget; Content creators, etc: YES, YES YES. But I would still buy a Xeon, if it was within my budget. Off on a tangent, Intel is top-dog right now, and kinda has been for 75% of my lifetime, after the athlon II x2/x4 and Phenom II X2/X4/X6 Days :)

The aging has nothing to do with the performance.SB is aging and is better than the first gen of Core i.similar to Ivy bridge and slighly slower than Haswell

Plus at 1440 the work isnt that big and.the 980 is just 10fps faster for 250usd more? The only way that we could see a change with the high end AMD and Nvidia gpus not yhe midrange gm204

It's pretty much the best CPU for gaming. Even if it bottlenecks, there's nothing you can do about it but overclock harder. xP

yes there is.you can use a low level api like mantle or directx12. Or use a higher resolution or get an i7 instead

I was talking about CPU choice, so API choice is a different issue~
But yeah if you have a game that's so advanced that it cpu bottlenecks with low level API, then going for more threads/cores is a good idea.

Looking forward to these games, personally.
