I just got a "Sapphire 7970 Vapor-X GHz edition" card and I just love it so far, the sound level etc. But I think I got 1 problem, and that is fps drops? NOt 100% sure yet but Bordlerands 2 dropping to 20fps sometimes, both big areas and smalls, bf3 get some small fps drops down to ~30, this is all whit max settings such as ultra in bf3, and maxed in borderlands2. Havent tried more games so far but.. It kinda feels wrong with fps drops random like this.
First though was that my cpu bottlenecking abit, but can it? 4GHz quad core shouldnt in single player games?.. And second though that might be it is that atm I have only connected my 2x 6pins PCI-E power cords into the card with 2pins extra in one, so its 8pin + 6pin connected. When I read about the card it said it only needed 8+6pin and that is what I have on my pci-e power.
Now I got converter from power -> 8pin power. So I can fix so I get both to 2x 8pin instead of 8+6. But wanna ask first if its cuase of that before I rearrange cables etc.
My PSU is a 700W Cooler Master silent pro, and my cpu is Phenom II x4 965, oc'd to 4GHz. 8gb 1600 ram and a gigabyte 890GPA-UD3H mobo.
I have cleaned drivers with Driver Sweeper and installed fresh 2 times, so its not that atleast
Im ready to reinstall windows if its really needed too.. But ya
