I have an assembled gaming/professional PC with those spec:

Intel Core i5 CPU 750 @ 2.67GHz 2.67GHz
8,00Gb RAM
Nvidia GTX 970 Factory Overclocked
2x 500Gb Hard Disk + Samsung SSD 250 Gb ( C: )

Two month ago I wasn't having the 980 but the GTX 240 (Very Bad GPU) and Black Ops 2 for Steam was running semi-well with constant 60 FPS.
Now that I have the GTX 980 the game is unplayable, totally laggy and costant 10 FPS.

Does anyone know why I have this problem and how can I fix it? It seems very strange because I can run GTA V all maxed and it doesn't minimally lag! I haven't this problem with any other game a part from BO2... Please help I don't know what I have to do.
I have also tryed to change the graphics setting to min. but nothing changed...

P.S. Sorry for bad English, I'm Italian xD
