what resolution you aim to play at and expected games?
There is a site that rents out cards, which I checked out after a youtuber praised them but the rental prices are insanity so wont recommend it.
if you know its going to be temporary prior to 500 series launch then I would go for the cheapest one.
I suspect AMD have a deal with the console vendors to make their SoC systems more powerful than what they sell as discrete which would explain why they not going into high end performance territory in the PC space. With that said tho I read rumours that the 500 series could hit gtx 1070 levels of performance for mid range price.
Regarding temps, go for an aftermarket card, prioritise heatsink thickness. Going for a card which could be considered too powerful will lead to lower temps as it wont be working at full pelt. Nvidia didnt really get cool until pascal tho in my opinion. Pascal temperatures are unreal. My gtx 970 would still hit mid 70s or higher in heavy games, my 1070 is 40s in most games, but enters the 50s if pushed. I can only get it higher than 60 in benchmarks.
