I wasnt aware nvidia made a 950.... its probably inline with the 650ti/750ti just again.....newer architexture/ less power consumption.
Id really try to squueze for at least the 760 or similar tiered cards. It wouldnt be fun to get everything done and find fps drops.... Ive read this game suffers with even slight fps drops causing your special moves/combos to drop.
Ive built my own computers since windows 3.1 and before the pentium even came out. On every build I went with the budget bang for the buck video cards (gt 9600, 650ti - being the last 2) I always just scraped by in terms of performance.
My last upgrade I splurged and bought an r9 290 and wow! it was a beast! You can get them cheap used on ebay - alot were old bitcoin minning cards being sold off.
Mine gave blue screen errors and being impatient I sent it back and got my gtx 770 OC .... same price as the r9 290, lost a tiny bit performance but this thing is super stable.
Huge improvement over the 650 ti which I felt was almost unplayable with newer games.... so Id hate to see you get a similar 750ti and be disappointed.
For mkx I say save and spend that extra $50-$100 and get at least a proper card to run this game (760 at least)
these are the cards Id look at for a mkx based build...
Lower tier/cheaper towards bottom....but wouldnt get anything less than whats on this list
I didnt list the really expensive ones....tried to keep it in the sane price level
