That is what I eould get.  P45  over clocks higher than X48...has 2 pci-e 2.0 slots (true will only opperate at 8x in Crossfire).  It is extremely well made has excellent layout, dual bios and runs cool, had e good manual and very good support.  Asus has gone to shit in last year or two.  X48's are too expensive and none have the 10r southbridge that I know of.  I recomended one to Glimmerman and he absolutlyloves it.  A lot of board for the money.
