What is this 333 you are talking about? Are you taking about USB/SATA, the 3-3-3 that Gigabyte advertises?
Asus P7P55D E PRO will be a nice choice It has usb3, sata 3 and also has plx bridge too. Motherboards without plx chip will cut down x16 pcie slot to x8 when using usb & sata 3. The board also supports sli or crossfire at x8/x8
