I recently built myself a new PC and everything has been running fine. However, in GPU-Z under 'Bus Interface' it states 'PCI-E 2.0 x16 @ x8 2.0', before any of you ask the GPU is in the slot closest to the CPU and it shows up as x16 in the BIOS.
System specs (might help):
GTX 560 Ti
Any help would be much appreciated! And I was wondering if someone could point me in the direction of another program that will show me this information, just in case it is a bug with GPU-Z.
I had the same bug in GPU-Z, but before I could even say "WTF?!" the 8x disappeared and was replaced with 16x. Also, it sometimes shows that PhysX is available and sometimes that it's not... If it shows up as x16 in the BIOS, I think it's alright.
