pci express 1x to 16x affects performance? Well, i bought Fx 6300 black edition and Gigabyte ga-78lmt-s2pt but it didn't detected both of my Graphics card (Zotac GTX 650 1gb DDR5 and XFX Radeon HD 5450). I tried both graphics card on my friend's pc and it's working fine. So i think My PCI-E x16 is dead so, there's any option to repair it? Or should I get pci express 1x to 16x adapter and will it affect the performance.
