Okay, so my problem is that i get lag in most games. Singleplayer in new games work fine, but multiplayer is just screwed! I get maby 40fps when playing multiplayer bf3, about 75 in campaign. The very odd thing here is that older games like Fallout NV isn't playable at all. I get 15-30 fps when playing it. I have tested my ram, no issues. I've overclocked my cpu, tested it with prime95, checked if it is overheating, but no errors, works ferfectly fine. I have installed all the drivers, updated the BIOS and DirectX, but still no change. In BF3 it doesn't do any good, changing the graphics, but strangely it does in Bioshock Infinite. Bioshock works fine, except some lagspikes now and then. I have had this problem in over a month, and i cant think of ANYTHING thst could be causing the lag. I would think that the cpu is the problem, but i've asked several cpu experts and they say that there's nothing wrong with the cpu. I also know several people who has the same cpu as me, and they are having no problems with it, and it runs all games fine. So, now i wonder if it could be something with the graphics card? My specs are:
Gigabyte 970A-UD3-mobo
Asus hd 7850-graphics
GS 600w corsair-psu
4gb XMS3 ddr3-ram
AMD FX 4100-cpu
1TB seagate-hdd
