Need list of good rendering GPUs

Hardware GPU
1

so i use cinema 4d, audocad, premiere, photoshop, maya, 3dx max, nuke, bouju, and really things like that.... wondering if you could give me a few price brackets with the best gpu setup

 

motherboard : 2 pci 3.0 16/0 or 8/8 speeds

-------

psu: 650w corsair 80 silver ( tell me if this needs to be upgraded to use a new config of video cards )

-------

cpu: i7 3770k @ 5ghz

------

ram: 32 gigs @ 2133

------

CURRENT video card: hd radeon 7870

-----

NOTE:: i play games, i run tripple monitors ( 1 32 inch @ 1920x1080, and 2 shimian 27 inch @ 2550x1440 ) but i really only play on the 32 inch since most games i just run at 1920x1080 anyway and the screne is bigger)

 

i know cuda cors help but i heard the open gl helps in 3d, i do TONS of 3d ( check out my stuff if you want to know what i am acually doing to help me out a bit better ) ---->

that depends entirely on the program, AMD GPUs are incapable of doing CUDA whereas Nvidia GPUs do OpenCL very poorly, to the point that a 5830 will outperform a 680 at OpenCL

now you see where im having troubble, most of my stuff uses openGL, but i dont know if there are any amd cards or nvidia card configs that out-do eachother for less money, like how you can quad-sli cards to out-perform high end gpus.
