The 780 wrecks the 760. WAAAAY more than just a 7% performance difference. SLI for the most part is garbage and buggy, go with a single GPU whenever possible. If you apparently have all that money I find it strange that you're going with a lower tier graphics card; the GPU is the most important aspect of a gaming PC
No offense but it sounds like you are just randomly spending money for this PC
