I installed today GPU-Z 0.3.7 just to check my graphic card Sapphire HD 4890. I noticed that it shows my card supports PCI Express x16 v1.1, but i know my card actually supports v2.0. Same goes for my motherboard too, it has support for x16 v2.0 (FX48 in a Shuttle SX48P2 Deluxe). I tested with both 0.3.6 and 0.3.7 versions of the application and also 9.9, 9.10, 9.11 drivers of ATI (i use mostly 9.10 driver which is really good compared to 9.11). Is it any problem with GPU-Z or maybe it is a problem with my card? I'll atach a pic so you can see.
