please help me choose which cards to get

[kamilalaa]

so i want to get 2 graphics cards to run in sli, so im choosing between 2 gtx690s, 2 gtx 780s, and 2 gtx 780ti
2x gtx 780 cards will be worth around 1050$
2x gtx 780ti cards will be worth around 1450$
2x gtx 690 cards would cost me around 2000$
i dont want to spend too much money but i want to get a really good performance, so what is the best performance to price ratio??
is it worth paying 2000 for 2 gtx690 cards (i know they're 2gpus each) or do i go for 2 gtx 780s or 780tis and maybe add a third one later?

2 780ti's is the best for performance-price ratio and you could slap another in later.
