You can't say that... You can always "run" it, it's just a question of what resolution you're running... AC Odyssey can also be played with a gtx 1050 at 1440p with minimal settings... and it also depends on the games... in principle, the 1070ti is a very good graphics card... i wouldn't worry about it... the 2 (moni and graka) fit very well together... the moni does whatever you tell it to do or the graka does... but how smooth it is in this case depends on the graka 😀
