While I am personally waiting for the full release before applying this, just to clear up some misconceptions about what this will do for your card:
Your highest stable overclock will probably not change. What will change is the sustained clockspeed throughout. For instance, my card does 2100->2070 (depending on how high temp gets) rock stable. HOWEVER once I hit the 400W power limit, my card has to sacrifice these boost clocks, and drops me down to 1985-1999 or so.
In theory, having another 50W for the graphics card will not have me hit that power wall and my 2100-2070 clocks will stay stable throughout. That will give an overall average frame boost when gaming for long periods.
If you are running at 1440P or 1080P, you may not even be hitting the power limit wall and won't notice much difference. This really shines when you're running at 4K or upscaled 4K. In CoD Warzone at 1440P, i never hit higher than 370w or so. My clocks then always stay at 2100-2085 etc. Once I cranked up the resolution to 4K, it hit the power limit and my clocks dropped to the 1985-1999 as mentioned.
One question though, I don't mess with the voltage slider. Has this helped anyone get higher clocks? I found after 2100Mhz, these chips are very unstable. I am able to run benchmarks at 2150+ but thats about it.
