Gtwilliams :
I have a phenom ii x2 @ 4ghz, 8gb of ram, an ssd and an Msi amd r9 290
Yes it bottlenecks your R9 290. Pair it with any of the FX 8xxx processors or even a FX 6300, for any meaningful full potential performance of R9 290.
Even if it's phenom ii x2 565 BE, it will not to be able keep up with that monster GPU.
Cheers!
