EmperorXIX :
I'm talking about the ASUS STRIX series, the one I will be getting is the STRIX-GTX750TI-OC-2GD5, but I will most likely upgrade later on.
Hope this helps.
Why not get a GTX 1050/1050Ti? Essentially same price for better performance. Unless you're getting a good deal for a second-hand card.
You will be able to overclock it, by how much is probably minimal, as overclocking the GPU brings almost little to no performance gains depending on the card.
That GTX 750Ti does have a dual fan cooling system so it will be able to keep it cool, that is on top of the fact that it is a really cool and quiet card. But with it not having an additional power source I doubt the overclocking potential is major.
