Those users who would like to build an SLI graphics subsystem have very limited options when it comes to choosing mainboards for LGA 775 processors. Nvidia nForce 6 series doesn’t support contemporary Intel processors, NVIDIA nForce 780i SLI and nForce 750i SLI run very warm and unstable during overclocking. You could take an NVIDIA nForce 790i Ultra SLI based board, but it is hard to spend $300-350 on a mainboard alone. By the way, EVGA offers their EVGA nForce 750i SLI FTW for almost $200. Not too cheap as well…
Don’t you think it is strange that ASUS and MSI decided to design their own Nvidia nForce 750i SLI based mainboards although they have pretty much the same features as the reference boards? Maybe the price is the reason? Although they have to invest in development, manufacturing boards of proprietary design is usually cheaper. For example, ASUS P5N-D can be purchased for 25% less than EVGA nForce 750i SLI FTW.
Anyway, we can only leave the decision making to SLI fans here. You may either use only one graphics card, or give up CPU overclocking altogether or overclock to pretty mediocre speeds. You may wait for new Nvidia chipsets or even switch to ATI graphics cards. The choice is yours, and at this time we cannot recommend any Nvidia nForce 750i SLI based mainboards. None of them are really good, so no wonder very few companies have them in their product range.
