Dayum.. I can buy two of them max.

For 3 cards i'd probably need a 6 core CPU too right? My poor old 3770K will probably bottleneck.

So 2 x 290x 8GB in CF won't yield any good results ? How does it work Kaapstad. Do you need the extra horsepower for the VRAM to become useful?

With two 8gb cards you won't have the GPU grunt to make use of it most of the time.

With three cards you may get the occasional opportunity to get over 4gb with the grunt the cards have got.

With 4 cards you can just turn everything up to max and in a handful of games you will be using about 5gb of VRAM. BF4 for example uses less than 4gb with DX11 and more than 4gb with Mantle. Crysis 3, RTW2, Skyrim modded are others that will go over 4gb.

Where it all goes wrong is when you get a badly written game that does not support CF/SLI.

Another thing to consider with 3 or 4 non ref cards is you need to look at watercooling to get the heat out of your case.

As written in another thread 3 x 290Ps would be a good compromise. I would be surprised if you need the extra AA that a 4th card would allow you to use.

As to intel Hexcores there maybe a couple of games that can make use of the extra threads.

So I have been playing with the 290X Tri X OC. Learned a couple of things..

Mantle seems to be the real deal. BF4 running under Mantle is really nice. Smooth fluid and no FPS drops.

Also learned that 290X's run hot as hell in Crossfire :p

If only it was winter...

Mantle for BF4 is top notch unless you want to play @4K.:)

In the 80c's. They generate a lot of heat in the case. My Antec 920 is struggling to throw it all out of the back of the PC :p

Might have to install some fans in top of the case.

I get a similar problem with my air cooled GTX 690s, the heat they throw out has to pass through the Rad used to cool the CPU meaning it is always running about 10c hotter than it could with watercooled GPUs.

Crossfire IS toasty!! I had reference cards, imagine that :eek:

I think the Tri-X cooler will stave off throttling over the Summer, it was pretty warm today! Excellent cooler tbh, more than happy with mine. Would have cost me more to get after-market cooling than I paid to switch lol, it was a no-brainer :cool:

This is toasty.:D

The card may be fine to run in the 90's, problem is it raises the temp of everything else along with it.

Watercooling would be ideal, I'm just gonna add more exhaust fans and hope for the best.

I'll have the last laugh in winter.

You get the same problem with watercooling, it does not matter whether I use air or water to cool my 290Xs as the heat from them still gets dumped into my room.
