InsaneGuy :
the reason is i want play some older games in 1080p. they just look better on 1080p. new games support nice 4k. but old games look somtimes weird in 4k.
gtx 970 with 4k works pretty well for me. i dont have any problems on framerate. espesially when turned on g-sync game always looks really fluid without tearing. and i dont like AMD. they too loud, too much heat and they are not as efficient when it comes to how much watts they consume.
i am really happy with my gtx 970 i always have min. 60fps when playing on 1440p and 50-60 when playing in 4K.
Are you kidding me? Sapphire Nitro R9 390 is one of the MOST effieicent cards out there, period. Not trying to start a fight, as to correct a half advised individual. Have you even owned an AMD card? Exactly. The GTX 970 is
the 1080p card. A R9 390 will outperform the 970 at 1440p and 4k, respectively, as it was created for those resolutions.
As for your 970 with magical powers; I've owned countless 970s and 4K is but a dream from 25-45FPS.
P.S, 50 FPS is pretty much IDLE.
I don't know where you get your framerates from, you're saying that your 970 at 4K matches the framerates of a 970 at 1080p, which is ridiculous.
