I have a 28 inches 4K monitor and a EVGA GTX 970 4GB vidcard. It's not enough to play PC games in 4K resolution, but it have way more than enough power for MAME with HLSL / GLSL /BGFX enabled at 60 fps.
I just tested a few MAME games at 3840x2160 res with HLSL enabled before writing this reply and they all played without lag, using between 17% and 40% of the GPU.
I don't have many heavy MAME games but it was enough for "RC de Go", "Gradius 4", "Simpsons Bowling".
If you know of a very heavy game in MAME, please let me know and I'll test it here for you.
With a 750ti you might still be able to run older MAME games at 4K resolution (elevator action, metal slug...), I would recommend a GeForce GTX 960 (either 960 or 960ti). I will probably be enough for 4K MAME games with HLSL enabled. For some newer games, you might want to lower the screen resolution to 2560x1440. Games look pretty darn good at this resolution in my 28 inches 4K monitor (gaming at 1920x1080 resolution looks like crap).
A GTX 950 might be enough, but I doubt it. Emphasis in the word might.
You don't need a GTX 1070 if it's just MAME games.
