As Aaron is likely to be doing tasks that make use of more than 2 cores (such as compiling) then the dual core i3 *really* isn't going to cut it, you're literally doubling the time it takes to perform such tasks with that option. There are even MAME drivers that make good use of more than 2 cores so it's not really a good option, especially not if you want something reasonably futureproof.
Trying to be cheap when it comes to the processor is the biggest mistake you can make.
