Gtx 780 bottleneck

[FrostBiter]

As I bought a new gpu, I didnt notice that much of a difference while it should give me a 30 percent boost on average. My cpu is a AMD Phenom II X6 1050T 2 Ghz

Thanks in advance

Edit: 1055 2.8 Ghz

Depending on the game you could have a big bottleneck. In the games you are playing what is your CPU and gpu usage during the game?
