The Sabertooth is unnecessary. Great mobo, but will you really use all the features? You'd probably be fine with a cheaper mobo. 750W is too much. Get a 600w. The 7950 is better than the 660Ti and is the same price or cheaper. No point in getting 1866 RAM. There's no tangible difference b/w 1866 and 1600.
^+1 to everything he said.
The Sabertooth is a gimmick. If you need all the features, it's basically the ASUS P8Z77-V PRO and the ASRock z77 Extreme6. Both are CHEAPER.
The 750w is overkill, yes. Though if you are planning on adding another card in the future for CF/SLI, then keep it.
If you're using a single monitor only though, make sure it's 120Hz since that's the only reason to add another card for SLI/CF.
Right. thanks now for the hunt... with the cpu cooler i am getting the mobo is a tough one any suggestions on a good mobo for gaming with spacious room for the massive D14
Don't worry about the motherboard. Look at RAM and casing clearance when dealing with CPU coolers.
