Someone wonder does shadowplay affect performance so I test ACO again but without recording.

Working great and realizing its potential are two different things. At 1080p any CPU from that generation holds FPS back - especially with such a high end card. Surely you are getting 60 FPS, I get that, but its putting a glass ceiling on the card.

The so cald glass ceiling you talk about whas not so bad in the beginning, but as of 2019, games has become to much for the old cpu and as i planning to get a second gtx 1080 ti for a sli setup. I am planning to replace the old hardware with a ryzen 9 3950X when it comes out and then the glass ceiling shut be gone any way.

Well, that's true, but what do you mean by old cpu?

My current CPU I7 980X came out in 1Q2010 and we are now in 3Q2019. So my cpu is over 9 years old now and if that is not old for hardware, i dont know when its old.

I added a 6 core Xeon to my X58 system, it's running 4.5GHz and 75C in games.

At 4.5GHz, it's within 10% of my 6 core 3930k socket 2011 system at stock clocks.

I get full framerate out of the 7970 running a 2048 x 1536 at 75 Hz.

Crysis looks beautiful on a CRT, btw. :)

10% is significant, especially since you are running above 1080p resolution pushing 50% more pixels which makes it more GPU bound.

A 7970 also isn't a very powerful card in the first place. Put a modern mid-range card up there and that glass ceiling I keep talking about becomes more apparent.
