I want to put Snow Leopard on my computer. I have a Dell Inspiron 6400. CPU-Z says my SSE is (1,2,3). Can I run all 3? Because I need SSE3 or Snow Leopard. My specs are: 1gb ram or 512 (not sure?) Intel® CoreTM 2 Duo Processor T5600 (1.83GHz/667MHz FSB/2MB L2 Cache) 64mb Graphic card 160gb HD. Can I run it? I have the Disc for it.
