AMD Phenom X4 9750 Quad Core Processor - 2.40GHz any good?

I'm getting a nvidia gtx 460 1gb, so I wanted to know if Phenom X4 9750 Quad Core Processor - 2.40GHz, 2MB L3 Cache, 3600 MT/s FSB, Quad-Core, Socket AM2+, OEM Processor would be good for gaming or not. I heard quad cores are not really good for gaming because most games only use 2 cores, so would this processor still be good for gaming?
