Six 975X Enthusiast Motherboards for Today and Tomorrow

Gigabyte's GA-G1975X was one of the first 975X-based Socket 775 motherboards on the market. However, only the current revisions will be able to support Core 2 Duo (Conroe) processors.

Due to the active cooling system that places two small fans to the left and the right side of the back panel, there are only a few connectors left.

It looks like the venting holes are smaller than the fans, which means the air flow will be rather limited.

    has anyone ever tested this (my) MB with a core 2 duo processor? Does it work?
