Hello everyone, i recently got back with my trip to US and came with a Z97-G95 gaming from the MSI and another r9 290. All looked well, but when i started to assemble my PC i have discovered an ugly truth. The middle one PCI-E 3.0 from the MOBO, isn't working and does not even reconize the gpu.So i decided to put on the last the second gpu on the last slot and that run's at 4x (and on the first one at 8x). Should i worry? this will affect my performance? picture below its showing how my pc is assembled.
