Core i5-580M vs. Core i7-640M - Page 2

post #11 of 12
the high end i5 duals and i7 duals are too similar to say that there is a noticeable performance difference. Get a laptop is the cheapest and better graphics card.

The 640m is a 35w, dual core/four thread processor, roughly the same as the i5 mentioned in the OP. It all really depends on the price. Get whatever's cheapest.
