[quote]One thing to mention unless your going to water cool your 3 GPUs you want to get a motherboard that puts at least one gap between the cards. The current cards heat up allot more if there no gap between the cards, this means it'll run its fan faster, so putting 4 back to back without water cooling will probably spin the fans up to an annoying level. The best option is to wait till they release a 2GPU card and get 4way SLI with two of them.
I saw Nvidia recommend this too, but can't remember where... :oops:
One important thing for others that read this thread, is that there IS single card support:
# Single card
* GeForce GTX 295
http://www.nvidia.com/object/3DV_System_Requirements_Surround_Technology.html
So if there will be a 2 GPU card with GT100 or 104 chip, it will probably support Nvidia surround as single card solution. :)
Seems that Nvidia has updated their system requirements page and now the GTX295 isn't listed as supported at all:
# GPU support (NVIDIA SLI or multi-GPU cards are required)
* SLI configurations
o GeForce GTX 480, 470, 285, 280, 275, 260
