Are any of these gpus compatible with my MSI motherboard

[computerthings]

I am looking to buy one of these Nvidia gpus second hand: GTX 960 / GTX 1050 / GTX 770.
Are any of these or all of them compatible with my MSI H55M E23 motherboard?
I just want to be sure before I go out and purchase one.

SPECS:

I am going to upgrade to a 450watt psu
I have a core i7 870
4gig ddr3 ram

all are but the 4gb of ram will hold you back

Thanks for the very fast response. I'm planning to upgrade to 8gig in the future.
