That would really suck because i bought this board for Crossfire and really thought it supported 2.0 x16 for both lanes in Crossfire.
Standard P45 using 2 slots = x8 but unless you have two HD4870x2's there is little performance difference with PCI-E 2.0 as there is so much bandwidth available in any case., although the more powerful cards the higher the performance hit generally but we are talking like 2-5% across the board here I think.
