Most definetly not, and I'm looking at that AMD Phenom 9500, not that it wouldn't be compatible but it is hefty bottleneck on performance.
You also need at least a 1.1 PCI-Express x16 slot on your motherboard to utilize sufficient bandwidth from that card, and you haven't listed your motherboard I couldn't say.
I say if you are going to shoot for the 480, I'd only buy it if it was around $140 or so. It has great performance at that price but I would discount it's validity based on its insane heat and power consumption. Another concern would be what is your current power supply?
What I would recommend is savin up for a new computer build that would include that graphics card (if you are still partial to it). Otherwise it will stick out like a sore thumb of disproportionate power as the CPU will bottleneck you making the 480 pointless :/
