Two typos...
"and a lover graphical impact than MSAA. " No idea what lover graphical means
Then it should be the addition of TAA not MSAA.
I don't think it's a negative at all. People need to get with the times. Multi GPU is dead and has been and newer technology such as TAA which is becoming very popular is part of the reason why. I mean sure it's great for the few who use it but realistically speaking the amount of effort required for it to work is pretty high for not much gain in many areas for a business.
DX12 should help but it's taking a while to get working in general let alone a niche mGPU feature.
As for the requirements.. kinda steep. 1080p60 ultra needs a 1080? Damn.
