Well that depends on the GPU you finally choose, but you can play 1080p with mid-high settings with any of the cards you listed in the first post.
I think I'll probably go with either GTX 950 or 960. Do the different models of those two particular cards make a major difference in the performance?
Not a major difference, but 960 is better than 950, the three cards you listed aren't in the same tier and price though, the 950 being the cheapest and the RX480 being the better one. That said you should buy the better one that fits your budget.
As in will the different versions of the two cards(like there are so many different sub models?) make a major difference?
Also, I read somewhere that the motherboard bios has to match the card or something. Can you explain what it is to me and if I'll have any problems regarding that.
