Wasn't aware of that. Even more, wasn't aware that two of those cards could beat a single 690 when 680 SLI barely does it |
The amount of OC you can get from a 660 card is pretty ridiculous so it's not really an issue(you can OC the 680s pretty well too, thought outside of PhysX, I see no reason for Nvidia for gaming since the price performance ratio is usually pretty uneven), the limiting factor is usually the PCIE bandwidth and PCIE2 was running out usually at more than 2 cards unless you had another controller to handle that on more expensive motherboards, it's better with PCIE3 so you will see 690 having a better turn out but that's still only doubled per lane and the most important equation is the cooling and power requirements on a single card vs dual card, in a lot of cases, you just can't run a single dual GPU card as high due to heating and power issues whereas you have more head room to OC single GPU cards on more stable power and vent heat better as well.
Of course, you could always do a good liquid cooling setup that connects your CPU, RAM, and your GPU+the GDDR RAM and clock the shit out of those, not exactly required but if you want to have some fun, that's how you do it, just make sure you have a board that won't shit on you in like a year lol.
