Question Videocard for PDAFT: collecting info about videocards working with game

Hi to all Project DIVA Arcade Future Tone gamers :)
I have very important question for you all.
I planning to build my own arcade cabinet and one of the important things inside that cabinet is it's "brain", a PC with certain parameters, but there may be deviations in one or another direction and that possible deviations I planning to define, because:

SEGA NU SPECIFICATIONS:

• CPU: Intel Core i3-3220 @ 3.30 GHz
• Main RAM: 4GB DDR3 SDRAM PC3‑12800 @ 800 MHz (12.8 GB/sec)
• Storage: SATA
  • 64GB SSD
  • 500GB HDD
• GPU: NVIDIA GeForce GTX650 Ti @ 980–1033 MHz
  • VRAM: 1GB GDDR5 @ 6.002 GHz (192‑bit, 144.2 GB/sec)
  • Features: Supports DirectX 11.1 and Open GL 4.3 with two screens in full HD
• • Core units: 768 unified shaders, 64 TMU, 24 ROP
  • Fillrate: 23.5 Gpixels/sec, 62.7 Gtexels/sec
  • Floating-point performance: 1.50528 GFLOPS

I going to use totally same PC, but there is still no graphical card.

So. that I mean?
Because of that damn mining hysteria it's very problematic to find videocards at all (and at a reasonable price even more hard), so I want to figure out what exactly card can be used and to find best card from the worsts :D
ONLY NVIDIA, but other cards info welcomed too.
For example:
I suspect that GTX560 Ti can be somehow better then GTX650 Ti, but does someone used it to play? No info about that in internet.
Another variant:
I suspect that GT1030 can be somehow better then GTX650 Ti, but someone said that it has some problems with pre-rendered videos (I do not know why).

i hope you understand what I mean, because in network no info about that all.

So please tell what card do you use and with what problems do you face (may be it works good on 720p but have huge framedrops on 1080p, or I heard somewhere that some cards works better on 1080p, whatever), if you use card something like this.
Thank you very much! :)
If I remember something - I'll update thread, because from the start hard to formulate everything properly.

 

That's very important nuance, because at first I was totally orientated on original Sega Nu configuration, but now think that for Full LG it needs more powerful card. May be, if I'll be lucky - I'll grab GTX760 in days (but I'm not sure), and that's can be great.

Yeah, that's true, that is why I created this thread to understand some nuances of possible variants, because, as was written above, I thought that in graphical case power of 1030 can be nearly same, but it's not supports NVENC, that I didn't know, and it was pretty important remark.

I thought 1050ti is somehow smaller :) But maybe not all variants are small :(

 

Some time ago I found MSI GTX 960 2gb with more or less acceptable price, so I took it and now PC for cabinet are nearly ready :)
