Need help with buying a new GPU

Hello,
I'm a big emulation fan and i would like to buy a new GPU that would allow me to run in high settings and smooth performance all emulators from the 80's up to PS3 and XBOX 360 emulation and possibly maybe ps4 and xbox one emulation if any exist yet(?), It would be nice if it won't be noisy. What GPU's would you recommend me and from which brand and which model? I thought about Nvidia GTX 1660 Ti. Also, it needs to fit my NZXT H2 tower. Am i doing the right thing? Do you think i need a new computer as well? BTW, my CPU is not overclocked.

my existing spec is (about 5 years old):
CPU
    Intel Core i7 2600K @ 3.40GHz    33 °C
    Sandy Bridge 32nm Technology
RAM
    32.0GB Dual-Channel DDR3 @ 802MHz (11-11-11-28)
Motherboard
    ASUSTeK Computer INC. P8Z68-V (LGA1155)    30 °C
Graphics
    SMBX2450 (1920x1080@59Hz)
    Intel HD Graphics 3000 (ASUStek Computer Inc)
Storage
    3726GB Seagate ST4000DM005-2DP166 (SATA )    32 °C
    2794GB Seagate ST3000DM001-1ER166 (SATA )    32 °C
    931GB Samsung HD103SJ (SATA )    32 °C
Optical Drives
    HL-DT-ST DVDRAM GH22NS70
Audio
    High Definition Audio Device
Tower
NZXT H2


Thanks in advance!

1660 Ti is enough. Anything modern will be better than some iGPU that doesn't even support OpenGL 4

If you want better performance, you may want to get a new CPU though, that's pretty old

Doesn't rpcs3 focuses on Vulcan?

That's why you want a card that supports it
