RE your question: NO - GPU compute will NOT help gaming FPS. Enabling GPU compute on a Titan will only LOWER gaming FPS because of the lower mandatory clock speed. FYI - GPU compute helps with things like folding, image/video editing & encoding (ex. Photoshop, PremierPro, Sony Vegas Pro, some avisynth filters, etc.) along with professional number crunching (engineering/finance/science). There's a few other things (bitcoin mining, blah, blah), but if you primarily game, I wouldn't worry about GPU compute too much. .
After reading about it a lot, and then with your comment, I do think that a pair of 7970 will be better than a pair of 680. But I guess I will save up for 1 GTX Titan.
After reading some other posts, it seems that the "best" deal right now is actually the Radeon 7950 Boost. It comes very close to matching a 7970 with it's higher clock speed, though obviously a 7970 beats it clock per clock. 2x7950 Boost might = 2xGTX680 (just make sure you get 3GB 7950s).
As for the Titan, unless you're doing a lot of image/video editing & encoding (AND your software won't work/work well with AMD - my issue) or something else that requires strong GPU compute/acceleration ability, OR you don't like SLI/Crossfire or can't fit in you case, OR the games you play don't support SLI (older game mostly, but those probably are not that demanding anyway), OR spending $1000 on a graphic card isn't really that a big deal for you, I can't really recommend the Titan. I'm considering it because I do some video/imaging stuff (and software works with NVIDIA), and SLI/Crossfire is tough to fit in my case. Even so, given the Titan's overall performance, justifying the cost is tough for me to do.
My plan right now is to wait a bit (waited long enough already LOL), and see what non-reference Titans are released as well as if there's any update on NVIDIA's next gen release. Some speculate June for the GTX780. If the GTX780 is actually released by summer AND has full GPU compute like the Titan AND 384bit memory interface (i.e same thing as Titan, but just fewer SMX units and 3GB VRAM), I'll get that and start saving up for Maxwell (gah - it never ends!
). I'm sure the Titan will be better than GTX780 regardless (more SMX units), but at what I expect to be 1/2 the price of a Titan, the GTX780 (with those specs) is the better value (IMO). I'm planning on upgrading my system as well as graphics card (Ivy Bridge-E) so $500 or so matters. If a stock non-reference Titan somehow gave the same or close to (95%) gaming performance of a GTX690, then perhaps I'll get that and hold until Maxwell refresh. *sigh* It would be a lot easier if I had more money
For someone like you that (AFAIK) doesn't need GPU compute (or no GPU compute software compatibility issues - folding works just fine on AMD), I think 2x Radeon7950 Boost makes more sense than saving up for a Titan. Just make sure to get good non-reference, 3GB GDDR cards. That should serve you better for gaming even when you do go to 1440p/120Hz. Plus, the savings will help to buy that 120Hz monitor you want.
