My System is..
Motherboard= Gigabyte GA-990FXA-UD5 (bios version F10)
Proccessor= AMD FX X8 8150 SOCKET AM3+ 3.6GHZ 16MB CACHE 32NM
Ram= 16GB(4X4) 1600mhz corsair ram
HDD= 2x500gb WDB Sata HDD
Graphic Cards =MSI 2X AMD HD6970 Crossfire
My problem is i got seriosly low fps on everygame and i really need help because its really annoying trying to fix this like 2 months now.
FPS in games like...
World of Warcraft MOP(Ultra Settings with 1080p res) = Min 19-15fps-max 35 fps in main cities and 50 -30 other zones.
Witcher 2 = min 9fps max 18(ultra settings with ubersampling on Min 20 - max 35 ubersampling off..)
Battlefield 3 = min 35 max 50( 1080p res , all on ultra) it was max 80 when i was using 12.8 driver with 12.10 it drops to max 50 somehow + got texture flickering while looking far distance with sniper etc.
NFS Most Wanted = Min 19 Max 45 with all settings on ultra
Most people have better performance then me in games with same system + less graphic card somehow. Before this system i had
AMD Phenom x4 3.0ghz cpu + 8gb 800mhz kingston ram with gtx460 and i made raid 2xWD 500GB HDD .
I was playing rift with min 35 fps on 1080p + ultra settings supersampling on . Then i formatted my pc when i opened rift i saw my fps was max 20 with supersampling on. So i changed my graphic card to single HD6970. But this time it was 10 fps more better in all games. Some people said that my power supply (500 watt xilence) is low for that graphic card so i buyed a new one with 750 watt xilence. But i saw nothing changes. I thought my cpu bottlenecking so i buyed current system( on top) and i saw that only +10 more fps better in all games again. I dont think this fps is normal with this system i tried nearly everyhing but nothing fix this problem.Only i didnt change my hdd's yet. Now most people says HDD is the problem but i dont wanna buy something for nothing again.
I plugged my second graphic card to 4x pcı slot because of when i plug 16x both cards stick together and makes overheat problems. I just changed it 4x to 8x after i got longer CF bridge cable. Btw i tried second card in 4x - 8x and 16x pcı slots all gives the same fps......
Here is a bechmark result while second card in 4x slot with windows 7
