I would also suggest if looking to save cost and go second hand with proccy with 3rd or fourth gen , go for xeon e3-1230 + chips they are equivalent to i7 but available dirt cheap on ebay! plus 1070 looks to be the new value card, but some one looking at cutting cost can look into the new amd r9 480x launching in jun 29 for 200$ which is pretty good and Vr ready, and looks to be able to handle anything thrown at it! came to know this yesterday via
@funnyadit, im looking to may be upgrade my 7790 for this!
