My FTW+ has an ASIC of 60.4% and while that is low I bumped it up 100 MHz right away and no issues. 115 MHz was still stable in Heaven but 130 MHz crashed it so I'll have to buff the voltage. TDP barely scraped 80% without being increased and my old FTW only hit 1450 MHz with an overclock and it had a 72.8% ASIC. Seems LeviFig got a bad card in general because mine is already topping my old FTW. I will do more testing and overclocking because I do believe it will hit 1500 MHz no problem. I'd also like to add that it has very minuscule coil whine, barely hearable. A big plus there too. My old 660 had it a bit and my FTW had it quite a bit as well but this one is silent.
As long as it hits 1500 MHz, I'd say it was worth it. Backplate, little to no coil whine, clocking higher, MMCP cooler as well. All I lost was ASIC quality, so far so good though!
Edit: Also, my GPU isn't even hitting it's advertised speeds. So if I really wanted to I could RMA this GPU. I'm going to wait and see.
