I'm having some trouble with my new Gigabyte GTX 670. According to most reviews and benchmarks, this card should score around 8000-9000 on 3DMark11 Performance preset. However, when I run the Performance benchmark, I only get a score of around 2000-3000. Additionally, Unigine Heaven 3.0 on moderate settings only runs at around 25-30fps... this card should be getting 70+ fps in that program. I've also been experiencing framerate drops and freezing/stuttering issues in Diablo 3, Skyrim, and Crysis 2. They will all run at 60fps most of the time, but every now and then the sound will start clicking and the game will drop down to like 2-3fps. PC Parts: CPU - Intel i5-3570K @ 3.4GHz Motherboard - Asus P8Z77-V PRO GPU - Gigabyte GeForce GTX 670 OC Windforce 3X RAM - 12GB Corsair Vengeance DDR3-1600MHz PSU - Corsair TX750M 750W SSD - OCZ Vertex 3 90GB HDD - Seagate Barracuda 1TB 7200rpm I have updated to the latest nVidia drivers (301.42 WHQL). I have uninstalled old drivers and uninstalled the Intel HD 4000 Graphics drivers. I have updated my motherboard BIOS to the latest revision (Rev. 1015 I think?) The card is in a PCIe x16 slot (slot closest to the CPU). The card runs at either 980MHz or 1175MHz during the benchmarks, and during games. Temperatures hover around 50 degrees Celsius. Power usage is around 40% (is that normal? should it be higher?) In the nVidia control panel, all settings are on Default; Ambient Occlusion is turned off, Power management mode is set to 'Prefer Maximum Performance' instead of 'Adaptive'. I feel like I've tried everything, is it possible that my card is defective? Can anybody think of something I may have missed?
