Im thinking of updating my mobo. Im currently running a 295x2 & a 290x in trifire on the Asus Z87-pro. The Z87 pro only has a single 16x slot . To get the best amount of bandwidth to both cards ( or all 3 effectively) should i upgrade my mobo to one that supports dual 16x pcie/ The 295x2 has a plx chip on it so would getting a board with a plx chip cause any conflicts (like additional latency) or am I going to see performance improvements?
