I'm building a new gaming PC, it's going to have two Gigabyte GTX780's. My laptop has Windows 8.1 and I don't really like it. I'm wondering if Windows 8.1 or 7 will have the best performance and driver support for sli gaming.
 
Solution
Absolutely go with Windows 8. As lp231 said, there will be support for SLI longer with Windows 8 than with Windows 7.
Plus, Windows 8 is mooted to be faster, and who doesn't like speed?

Both have support for SLI gaming, but with Windows 8 being the new OS and newer games will be optimized for it. You can bet that later on, Windows 8 will have better performance and driver support.
Don't like Win 8.1's start button?
Try Classic Shell

According to some tests done by TechPowerups, the ASUS GTX 780 DirectCU II OC 3 GB version had the coolest temperatures. Sounds like that's the one to go with.

If you're going to be gaming, Windows 8 has become a necessity. Sure Windows 7 is home sweet home, but with 3rd party programs like Classic Shell, Windows 8 quickly becomes comfortable again and lets you avoid the "metro side of Windows 8" completely.
My grounds being, that games will be optimized for W8 as will drivers. Windows 8 has no problems at all with gaming or just normal computer use like many rumors beg to differ.

avoid 8.1 SLI has major problems in 8.1 (atleast in surround via firsthand knowledge, as far as nonsurround only what ive read) I had to downgrade back to 8 lest lose my ability to play ffxiv with sli enabled.

Weirdest problem ever. Aside from the driver hangs and the missing textures on the desktop.. via RTSS my cards would all show as fully loaded and heat up (atleast via rtss) to unrealistic levels, yet I would get performance equivalent to 1 card (with 4). I downgraded back to 8 and now my cards are getting between 70-95% performance and it fluctuates as you would expect instead of being locked at 99 99 99 99, and whether those temps were right or wrong, I got no SLI indicator and the performance was indicative as well of no SLI. Now my temps are where you would expect 60-70 and performance is doubled if not better. (oh and I get the sli indicator lol)

Anyways, im working through email and PM with a CSR and a QA engineer at NVidia to sort it out, but it may not make it into this rounds driver release (dec 8) so all you can do is try and hope your game is one of the ones that work and put up with the non game related bugs for now. If your GOC (game of choice) doesn't work, downgrade like I did.

So far standard SLI seems the most stable. Tri and Quad are having the issues (I fall in the latter)

Just FTR and for anyone who comes across this... after working w/ the guys at NVidia - they were able to reproduce it in the lab. They are now working on a fix. MUCH time wasted in denying the problem and/or assuming it was on the customers end BUT hats off to Josh at Nvidia for giving me the benefit of the doubt. He worked with me to confirm I did put my legwork in and wasn't crazy/ignorant (god knows they likely get MANY such cases. Anyhow its now out of my hands.

2 dozen reformats and a couple weeks later >.<
