For several years now, I've been using an MSI GTX 1070 Seahawk which is a water cooled GTX 1070, and its been amazing. It wont give you 4K output, but it will take a 4K setting and render it too your native resolution while maintaining most of the 4K quality. I personally cant tell the difference between 3K and 4K as my eyes are old and dont work as good as when i was young..
I use a 55inch widescreen clocked at 60hz for a monitor.
My Mother board is an AASUS ROG Crosshair Hero VII with 24 gigs of Corsair Dominator Ram capable of boosts up to 3200 MHZ.
My CPU is a Ryzen 7 2700 and cooling is provided by 16 normal fans and a coolermaster V8 GTS vapor chamber CPU cooler which keeps the machine below 65 degrees during heavy loads and 48 degrees watching you tube..
Results are:
X-Plane 11.50b16 @1920x1080 ( all settings maxed ) 30 - 90 FPS smooth using Vulkan.
P3Dv4 @1920x1080 ( All settings maxed ) 60 - 120 FPS depending on the plane
FSX @1920x1080 All settings maxed Too stupidly high to worry about..
Skyrim, 80FPS during combat
Oblivion, fallout3, fallout4 too high to think about, ever..
The 1070 is a tank that just flat out delivers, and at a current 229.00 dollars its hard to beat. In Fact, used Seahawks are going for upwards of 900 dollars I mean, look it up, I do not exaggerate. Other cards like the 1080 got all the glory, but the 1070 just keeps on giving in a way thats kept me delighted for over four years and will do so far into the future. In the still image below study the machines listed behind and above my ratings. Those are 2000+ dollar CPUs my machine was going up against and I trashed them with that 1070.. Its affordable and its magnificent. I cant recommend another GPU more highly..
