660 Ti SLI vs Upgrading to GTX 780?
I have the option to upgrade to either a GTX 780, or replace my single Gigabyte 660 Ti with two MSI Power Edition overclocked 660 Ti cards. I know that two 660 Ti cards in SLI outperform the GTX Titan in stereoscopic 3D, thanks to this video: https://www.youtube.com/watch?v=ix-2xPTSXm4, but I'm not running in 3D.

If you enjoy the power of an outdated gpu model, then the 660Ti looks good (cheaper as well). But gtx 780 is the new kid on the block and it rocks. Also, I keep telling people, get SLI at your own risk. You can get unwanted stuttering and tearing issues.

I have 2 660s in SLI and CANNOT WAIT to replace them with a 780.

It's really a stretch to consider the GTX 660 Ti as "outdated" comparing a GK104 GPU to its sibling GK110 - they're both Keplers with the distinction of having the GK104 designed as GeForce while the GK110 is an adapted GPGPU. That's not to say one is more appropriate than the other, as all of nVidia's GPUs since the G80 are primarily designed as more than just a "graphics card". But they're both still Keplers, and a choice between the two would depend upon anything you choose to do with the card(s) outside of straight gaming. One thing to consider as well is "future proofing". Your posting strongly suggests a tendency to upgrade often, in which case doubling up on your current level would not be as advantageous as the single-card option in the shorter term. If you need more power than the 2-Way 660 Ti can afford, then you can move up to a third - [b][I]if[/I][/b] your motherboard can handle it - and get, at best, only a 50% increase in performance. If your MoBo can only handle 2-Way, then you'll be further down the road with that pair of Ti's and their market value or find yourself replacing the platform that drives them. Although not as strong as a pair of Ti's, your short-term option of doubling that only involves having to get another 780 at what's bound to be a discounted price from Release Day. And there are those that would argue the performance issues of single-card ops vs teamed cards, but folks like me have been running SLI in various forms for years because we're satisfied with the experience and, in some cases, find the added flexibility advantageous as well. A properly-balanced SLI rig is a much smoother experience than you'd picture reading through forums, but you must consider the source of the forums' data. Are you running extreme resolutions or multi-monitors? The GTX 780 has the advantages of both more VRAM and a much wider bus for superior bandwidth. That's a hard point to argue with even for a fan of SLI like myself. Although I recognize the CPU model I'm not really familiar with AMD, and must use charts like the CPU Hierarchy at Tom's Hardware to see that it's on par with the extreme end of the Core i7 8- & 9- Intel series - which is a very good place to be whichever route you decide upon...

you should surely go in for GTX 780 if its in your budget.
