Hello, im curious if the problem is with the motherboard or videocard, first of all my MB is an AsRock z77 extreme4, now i just got a new Gigabyte 7970 Ghz edition card which is pcie 3.0 and 16x, prior to this card i had a radeon 5870 pcie 2.0 and 16x now that card shows as (PCI-E 2.0x16@x16 2.0) with the GPUZ program, now when i install my gigabyte 7970 card it only reads as (PCI-E3.0x16@x8 1.1) but 3.0 when running 3D application. My question is why is the motherboard only detecting it as an 8x card and not full 16x lane? how can that be changed to 16x like my old card detected?
