Get the ASUS P7P55D-E Pro for $190 over any of the two you discussed. It is the best all around (bang for the buck, features, performance, etc.) P55 motherboard you can purchase... IMO.
Just wanted to ask, If i insert a big graphix or smth like that, will it block any other ports? (cuz i dunno anything about layout)? Also if I SLI will it be 8x/8x???
thanks for answering
