I always owned ATX motherboards but I got tired of the big case size so I was thinking going MATX or even ITX but if it impacts my overclocking potential I'll stay ATX if I have to. Do I loose anything going from ATX to a smaller size? I overclock a lot my CPU, Memory, and Videocard I don't SLI at all I had nothing but bad experiences with dualcards. But I would like at least a bit of expansion ability for a sound card or SSD card in the future.
