Hi

Im considering adding another 7990 to my rig.

Currently i have 7990 ( xspc water cooled ) and a 7970 Vapor X 6gb

Im using the S1 Sniper 5 and i beleive i can add another 7990 if i water cool it and place the 7970 in the middle slot which will allow me to connect the 7990 either side of it.

Do you think this will work ? or am i heading for bug trouble in little China ?

Crossfire supports only four GPU's total.  Same as SLI.

Going from three 7970's to four would also net almost no gains, unless you're using a ridiculously large Eyefinity setup (i.e. three 30" monitors or more worth of screen real estate).
