It's a good thing that you are running a 1440p monitor, because the higher the resolution, the more dependent on the GPU - the CPU load stays the same across resolutions.

This means that dual GPUs scale much better the higher the resolution.
For example in the same game you can see only 150% performance improvement on 1680x1050, something like 180% in 1080p ,whereas on the same game you can get something like 197% if you are running 1600p or triple monitors, for example.

CPU load does not stay the same. It just does not increase as drastically as the GPU load does. The higher the resolution, the more all of your components work. The GPU just works exponentially harder.



This is the first time I have ever recommend this but, go with a Titan, your budget is there, no need to go with a dual GPU card. The VRAM will help you. SLI has higher frame rates, but comes at a cost, you get a decent amount of frame rate lag as well.

Thank you for all of the input. All of it is greatly appreciated. I am still narrowly considering the Titan but will it keep 60 fps with the next gen games? I wasn't sure myself that's why I was leaning more towards a dual gpu as it seems they offer more raw horse power. Any thoughts on what would be more future proof? Thanks

Also I have been meaning to ask about radeon pro. I saw a review a while back on Tom's hardware which stated clearly that using radeon pro with crossfire greatly increased the smoothness of gameplay. That being said wouldn't that work with the 7990? Unless I missed one I haven't seen a review that mentioned using radeon pro.

You are write. I swear I saw my mistake but I was to lazy to correct it tongue.gif
CPU doesn't increases as drastically as GPU load does thumb.gif

OP, check for "micro stuttering". It's a common problem with multi-gpu setups.

Generally speaking, a single powerful GPU is always better than a multi GPU setup with lower end cards.
SO I would also advice you to go with a titan. I didn't before because I though they were like 1400USD, 140% of your budget.

randeon pros are not meant for gaming, they cost a lot for their gaming performance. They are meant to do other things, such as 3d modeling.
Sorry, made a mistake of swaping the meaning of FirePro for RadeonPro.

By the way, consider that a titan or other cards could suffer from a bottleneck from you CPU....

Unfortunately maybe you would have to make a switch to intel...

Thanks you I will strongly consider the Titan. Also to make sure we were talking about the same thing the radeon pro was a software download that you create profiles for, kind of like the CAP's in CCC. And supposedly it helps smooth out gameplay while using crossfire. Will try and pull up the article when I get home, using my phone atm.

I didnt even notice that... yes OP you probably should get a high end card like the 7970 and grab an i5/i7.

Dafuq, those are FirePros you are thinking about.
He's talking of RadeonPro the application. Frankly anyone that has a AMD GPU and doesn't use RadeonPro is wasting the GPU. Seriously.

I'll feed you some cyanide if you think titan is below 1000$ ... the day when a titan (not some gimped version which might not even come) becomes 500$ is the day that never comes ...
