Hello, i recently purchased a 7850, which i am very pleased with except for some tweaking of the minimum clock to prevent the flickering issue, so much so i wish to purchase a second. I am using an overclocked 1055t (overclocked to 3.6ghz, 4.0ghz on TC) on an asus M4a89gtd pro usb3 motherboard which as stated before does not support dual x16 pcie2.0 lanes. Will using two 7850s without the dual 16x, instead only dual x8 lanes, create a bottleneck? Thanks. I will be running two screen (one 1680x1050, the other 1920x1080) however i will only be playing games on one screen at 1920x1080. Thanks!

there is absolutely no performance difference between x16,x16 or x8,x8.
