I am building a gaming/graphic system and was wondering if you can run SLI -AND- CrossFire on the same system. The motherboard is the Asus Rampage III Black Edition. I have two 24" Samsung LED's and two 21" Sony CRT's My plan was to run the LED's Off the SLI's and the CRT's off the Crossfire's. Anyone have any idea on whether or not this is possible? I am running Wondow's 7 Ultimate 64bit.
