I am looking into buying gtx 980Ti Asus Strix (hopefully for some decent OC) or one of the aftermarket versions of gtx 1070. However i am limited to a 600w PSU and a tight budget as a student. Here in UK new 1070s are priced at about 380£ to about 425£ on some pricier versions (492-544USD), while i as a student am able to get 20% off amazon warehouse deals and therefore gtx 980Ti Asus Strix with minor packaging damage costs me about 325£ (421USD). I would like to get some opinions as to what should I buy in this case (does the extra 2gb of vram, better power efficiency and some other features justify buying 1070). CPU is I5 4690k (which i also plan to OC)
