I could either buy GTX 760 now and new PSU for it (which is around 340$ in total) or wait a few months for new Maxwell architecture's GTX 860 to come out and if it has less power consumption, as new Maxwell GPUs are said/speculated to, then maybe I could just use my current PSU with new 860. New 750 Ti based on Maxwell architecture was super power sufficient so I've heard people speculating that new GTX 860 might require only 400w PSU. So I could basically save money on new PSU and put it in 860 instead, if it will be expensive than 760 now, or just save it completely if it would not be more expensive. Also I have heard people talking that new 860 may be even cheaper than 760 currently as it has happened before with new releases what ended up being cheaper than worse cards in past. Should I wait? Thoughts please?
