Hello, recently upgraded my CPU from AMD PHENOM 1055t x2x6 to AMD FX 8350 and wow I feel like the upgrade unleashed the graphics card 7970 that I had in with the 1055t. The performance and visuals are quite outstanding compared to what it was before. I hear the term bottleneck and I seem to think that was what was going on with the last CPU can someone please explain. thank you....
