With the AMD 965 3.4 GHz quad-core processor, you have enough speed to run nearly any 32- or 64-bit program on your computer. Four cores and a 3.4 GHz clock speed give the AMD Phenom II X4 965 enough power to run a variety of PC games and software programs at once. The Direct Connect Architecture found inside the AMD X4 increases this CPU's performance by directly connecting the CPU's various subsystems to each other. Made with AMD's proprietary Cool'n'Quiet 3.0 technology, this processor is as quiet as a mouse while exuding very low amounts of heat. The AMD Phenom II comes packed with a software CD that includes not only drivers but also programs like AMD Virtualization, which allows one PC to act like multiple machines.
