the GTX 1080 is going to be an epic card but is already making some previous buyer of the last greatest cards (980 Ti or even the Titan X) sick with Nvidia, as not only is it way cheaper than the last / previous card, it's way quicker, bit overkill for most, but if you want or are using dual cards etc for 4k screens, look no further, one card wonder, low power, fast as a rocket and half the cost of previous solutions, so great news indeed.
premium price atm on launch but once it settles down a bit might grab one in a year or so for my gaming rig
regarding Doom, looks good, but not really my sort of game either so not played it or seen much apart from online stuff, so enjoy if you have it...
The GTX 1080 is definitely going to be in my new rig! I don't think it is overkill for graphically intensive games (Doom, Grand Theft Auto V, Fallout 4...), don't you think Zak?
It is overkill for 1080p@60, and potentially 2560x1440@60 in my opinion.
