Hello,
if my motherboard has 4 Graphic card slots...can I run 2way SLI AND 2way Crossfire? I want to run 4 Monitors. 2x 24in Samsung LED's and 2 21in Sony Crt's is this possible. I was going to plu the LED's into the sli's and the CRT's into the crossfires...

Please let me know if this is possible...

A mobo can have the ability to run SLI and Crossfire. Therefore, if you have enough slots, you can. But you can't combine the two you have to at least have 1 monitor for each SLI/Crossfire.

if you have a mb with a Lucid Hydra controller then you can infact run the two together but you need a board like the Asus Crosshair IV Extreme but you don't get very much of a performance boost. Better sticking off with one or the other.

I was thinking of the Asus Rampage III Black Edition. My goal is to run the 21" crt's off the xfx crossroads and the 24" LEDs off the evga's SLI. I want to get back into graphic design AND want an amazing gaming machine. I will list my pc here within 48hrs. I am looking for some feedback as to whether or not this system would run.

I am pretty good with computers, just not the best at building them.

Jeff!
