ur probs not gonna like the answer, but for 160-200$, both are a massive waste. think of it like this, somebodies grandma is 100 years old, and needs life support. shes fine with dying, but you will end up paying thousands and thousands of dollars just to keep her alive a bit longer, thats what your doing. socket 775 is DEAD, its "son" is DEAD, its grandson is almost dead (775, 1156, 1366). it is a mssive waste to pour that amount of money into it, when you can buy a AM3 (most future proof and best value) quad core and a brand spankin new mobo for 160-300$, like this:

thats 159$! you may or may not need new ram, but even still its only a bit more expensive for an entirely new and better setup.
