I have a gtx 650 to boost 2gb gpu... I need a custom cooler for it.. If anyone can suggest me some good one.. Thanks
http://www.arctic.ac/eu_en/products/cooling/vga/accelero-twin-turbo-iii.html Keep in mind it's a big cooler now they added the Heatsink style Backplate. 3 Slots below the card. 1,5 Slot above the card.

Anyways, SLI is possible with the Twin Turbo 3, but as i said you need a spacious motherboard. It seems you need 4 empty slots between the first and second videocard. This guy uses the Xtreme 4 in SLI. http://forums.guru3d.com/showpost.php?p=4784812&postcount=9
No idea, i never messed with that. I been using Arctic Coolers for my Videocards for nearly 10 years now.
If you're thinking of SLi, then the cost of another 650Ti Boost + 2 custom coolers is better spent on a high-end GPU with good cooling out-of-the-box and sell your existing 650Ti Boost.
