The least expensive Windows license that's readily available is the System Builder (genric OEM) one. It's intended only for use on systems for resale, but there's no enforcement of that that I know of. Some vendors will cheerfully sell it to you without any hardware.

Has the usual OEM restrictions, but the price is enough lower to make it worthy of consideration.
On your second question, the I3 CPUs are dual core, and they support hyperthreading (4 logical cores show up in Windows). I5 is quad core, without hyperthreading. I7 is 4 or 6 core, with hyperthreading. Some of the I7s are Socket 1366 (old) or Socket 2011 (new).
