Okay at the moment I am still waiting for P45 motherboards to be released. I am starting to get impatient and was looking at X48 boards (especially as the only Gigabyte P45 board on Scan is a top of the range £170 one). Now on Scan they have the DS4 and the DS5 (can't link them as my post count is too low) and the only differences I can find is that the DS5 has 2 more internal SATA ports. Is that really the only difference between them for £15?
