If you do buy the Haswell i5 then I wouldn't bother with the 5570 any more. It's an old card with little to no use in modern games. The chipset in the Haswell series processors is much better than in the older generations, so if you aren't planning on gaming then you'll do just fine without a dedicated graphics card.
If you do plan on doing some light-medium gaming then the Radeon HD7770 is a decent entry-level card which will get you by fine in most things.
