If you're planning on streaming eventually, the bare minimum I'd be looking at is an i5, probably i5-4690k.
The problem is, in order to get something that will be worth buying, you're looking at breaking that budget by 30-50%. I wouldn't even waste money on a "budget" build, especially for streaming. Save until you can afford a decent upper-mid rig and it will last much much longer, saving you money in the long run versus upgrading to newer budget pieces very often.
