I agree, I wonder why no mfg. makes an nvidia 650i or 680i sli/ultra board in micro atx format. I think that'd be a pretty sweet setup.
The only nvidia intel boards are based on the 6100/6150 integrated graphics chipset, which is pretty average, and doesn't seem to like to overclock very much.
I just purchased the Gigabyte GA-G33M-DS2R mobo today. Curious question about memory though. I looked at their memory compatibility list and it only lists a max of 1GB chips. I wanted to totally max it out (8GB) with Corsair XMS2 TWIN2X4096-6400C5DHX. The question is: Do you think the mobo will have a problem with 2GB sticks even though its not on their compatibility list? It doesn't make any sense that the board can take 8GB, but them not listing 2GB sticks.
