I want to buy a new computer in the next 2 months. My budget is about $750 on gpus and $2500 in total I will be getting adequate power supply for the gpu I choose (850w or something) and I currently have a nvidia 230M on my laptop Will be getting a 3770 with a P8Z77-V mobo, 16gb corsair vengeance memory. My only website I can buy from is pcccasegear.com I prefer sapphire, msi, evga and asus cards. Not really fussed over AMD vs Nvidia I will be overclocking Monitor resolution will be 1920x1080 on a 27" or 24" 120hz

IMO the best dual GPU config today is 2 x GTX 670 so if you could make the gpu budget +50 dollars more that will be great. If you are limited to only 750 then go with 2 x HD 7950
2 gpus would be a waste at 1080p. A single 7970 would be the best considering its the fastest single card out there. Btw amd crossfire drivers do not suck.
