I am currently running 2 4850's in a motherboard capable of "Spyder" (Running 4 ati video cards). I run 3 monitors and find that I like keeping the 2nd and 3rd displays going while gaming (TV on one, Temp and other monitoring stuff on the other) while gaming on my primary. This means I dont utilize crossfire often.
My question is if I add a 3rd video card, when enabling crossfire can I enable it across two of the cards while still running the 3rd seperate for my other two monitors, or would crossfire have to be activated across all 3 cards at once?
Basically I want to have two cards running in crossfire and have a 3rd card still running two other monitors.... Also, will an ATI Certified Thermaltake Toughpower 750watt PSU be enough to handle 3 4850's. (Keep in mind 1 would draw less power since not being used for gaming and not being crossfired with the other two)...
Im not too sure if the crossfire and single would work but i would recommend an 850w psu. i am running 2 4850's with 2 hard drives and 4gb's of ddr3 ram and an msi x38 platinum and my 700w arctic power seems to struggle.
sorry i forgot, i am also running a q6600 at 3.2ghz
