A properly specified P-55 board Tags: Motherboards SATA Graphics Cards USB3 Crossfire Product Last response: January 22, 2010 10:11 PM in Motherboards Share Cackles January 18, 2010 7:21:38 PM Hi, I am doing my first system build soon. I was after a P 55 mobo with USB3 and SATA 600. However, I also plan to Crossfire or SLI the system. From what I can tell, all the P55 boards out there can have 2 graphics cards OR 1 graphics card and the USB 3 and SATA 600 controller working. Are there any P55 boards that can have USB 3, SATA 600 and SLI/Crossfire working at the same time? Thanks in anticipation More about : properly board dpaul8 a b V Motherboard January 18, 2010 10:18:31 PM Yes, you should consider the ASUS P7P55D-E PRO motherboard. http://www.newegg.com/Product/Product.aspx?Item=N82E168... This motherboard has a PLX bridge chip that allows both graphics cards and the USB 3.0 to operate without bottlenecking either compont. This is an excellent implementation of USB 3.0. http://www.tomshardware.com/reviews/usb-3.0-performance... Good luck.

RAID will also work fine. Can't find your answer ? Ask !
