x48 = x38

So p45 wont be any better than x38/x48 boards.
Why should P45 be better than X38/X48? P45 = mainstream, X48 = Highend!

P45 might be a better choice though, due to smaller structures and the double bandwith isn't needed by the graphic cards.

fixed and why does it run hotter? maybe the heatspreader causes this.
