If you are referring to the Phenom X3 8450, yes... your processor should be able to keep up with the demands of the GTX 560. That is, assuming you have a board with at least 4GB DDR2 or better memory, a fairly recent Hyper Transport version, and your gaming isn't done above 1680x1050 resolution. Bottlenecking is highly over-worried. Yes, it occurs, but it isn't a game killer in most cases. It just means your Graphics card will wait a cycle or so for the CPU to process the frames it sends. Remember... good gaming is mainly about the graphics card.
