what's your gpu intentions ?
I loved my x58 E760 from evga , but when looking at a high end board for a 3770k  I went back to asus [M5F] 
-waited a long time for the plx boards [FTW] ,only to see that for sli @ x8+x8 PCI-E 3.0 was the simpler solution , than the many add on switching chips that the plx boards require.
-so for me only ever to use no more than 2 gpu's , the FTW came off my list ,same with the other plx boards. 
-also the M5F waterpipe came free and fitted into my loop nicely.
-oh ,if I remember correctly I think the pci-e x1 would be covered when using sli , so no sound card.[FTW]
