If I was on SLI 780ti's ill be holding off for pascal. I upgraded from a couple of poor clocking 780 non ti to average clocking 980ti sli (1450mhz range) and I say it was a good upgrade as a single OCed 980ti was not far off my old 780 SLI setup.
That and the 980ti landed when I was playing the witcher 3 which I was looking forward to for so long and wanted to play it maxed out at 1440p with a solid 60fps, something I couldn't do with my 780's or a single 980ti without drops.
Its likely I will wait untill there's full fat GP100 card if a GP104 card is only 20% or so faster than a 980ti etc but we shall see
As much as this is about graphics cards, I can't get passed your 5820k being at 4.1 - don't you feel like it should be ran at 4.0 or 4.2. There's something disturbing about a 4.1 clock speed. It's like setting an alarm at xx:57 instead of 56 or 58
