I recently purchased an MSI 7950 to replace my old 7950. Although every time I try to overclock the card using higher than it's stock voltage games will constantly freeze or I get a black screen and the game crashes. I also noticed recently that I was getting flickering textures in some games. Although I had the same problem with my other 7950.
Could the card be faulty? I'm starting to worry that the PCI 3.0 slot on my motherboard may be messed up.
