yes I'm using a 1080P monitor, and that's my only issue, is this card seems really good and can handle all graphical effects really well (although even though it's a DX11 card, it can't handle DX11, it just kills it) but it doesn't run 1920x1080 very well. I'm thinking of getting a monitor with a native resolution of about 1440x900 or so, that way it will look good on the monitor (since it's native resolution) and the card will handle games MUCH better.
with this card, you pretty much have to decide, 1920x1080 with no effects/low effects. OR 1280x720 or around there and most effects/high. Also, it runs many things really well around 30-40FPS, and enabling all effects/turning up quality on most games really only takes a hit of about 1-2FPS, but trying to maintain 55-60FPS for multiplayer gaming is where you need to make the sacrifice. If you're ok with 30-40 (which I am for singleplayer experiences) then the card holds it weight quite well.
also, Rolli, I would NOT feel comfortable running ANY electronic component that hot! 70 is my ABSOLUTE max! And even in the 60s I get uneasy, but ya I think I'll bump it back up to the 905 core clock, cuz the temps were still under 50 so that was good, and past 905 and 1070, I started getting crashes after quite a while of gaming, so if I shortened play times I could ramp it up a little more, but I also don't want to reduce the cards life too much.
Hope I helped OP!
