i suggest you go for a AMD build right now, and just buy a whole new system for an ivy build of i5 soon when you get the money, with 300$ + some old stuff that you have lyiing around can fetch you a nice amd build (if you have any lying around) even a cheap psu is good enough and some cheap gpu's, then when you get the money go for an i5, amd on such a budget would be good enough, i suggest amd phenom 960T if you can get your hands on it if not get those phenomII x2 which are cheaper and some nice cheap mobo a good cheap gpu like those 512mb ones and your good to go
