Will the new Imac 27"r outperform my MacPro 6c?

[Mac Hammer Fan]

I own a Mac Pro 4,1>5,1 (2009) 512 GB SSD PCIe, ATI Radeon 5870 1GB VRAM 16 GB RAM with a 23 inch Mac screen that is ten years old. I can buy 4 GHz Imac 27 inch retina with 512 GB SSD 32 GB RAM and 4GB VRAM AMD Radeon R9 M395X or upgrade the current MacPro with a Nvidia GTX 970 or 980 2x6pins (no 8 pins), an USB card 3.0 Calldigit driverless and a Retina 27 inch Dell display. What would you do? Use the current MacPro as a second computer and buy the Imac or upgrade the current MacPro. The first option will cost me approx. 1250$ extra.
Geekbench 3,0
Mac Pro 6c 3,3 Ghz 14100
iMac 27"r 4.0 Ghz 17300.

From what I've read, the 5k iMac can and does out perform the current generation Mac Pro. So I'd say it will out perform a 2009 Mac Pro

This link indicates that the upgraded MacPro 6c 3.3 Ghz is faster than an iMac 4c 4GHz.

I checked the Cinebench test R15.
Current Mac Pro 6c with ATI Radeon 5870
CPU 798 cbu
OpenGL 71.18 fps (slower - old card)
Imac 27 inch Retina 4 GHz Radeon M295 X
CPU 721 cbu (slower!)
OpenGL 104.71 fps (faster)
Is there anyone who can post this one?
2010 Mac Pro 6c with Geforce GTX 980?

I have no information on performance of the Geforce GTX 980, but other items than just the graphics card come into play with how powerful your system is compared to the iMac and the potential yours has versus the iMac..

I would say keep and upgrade the MP and not even bother with the retina iMac until it drastically outperforms the MP. As it stands now, you have SATA 2 but 2 x PCIe 2.0 slots whereas the iMac only has 1 SATA connector and 1 PCIe connector.

You could VERY easily outperform that with a RAIDed system with all 4 HDDs in RAID. If you already have those drives then that involves no extra cost but simply a reformatting and reconfiguration. And if you have SSDs in each of those slots, that would be AMAZING.

I see little reason to get the retina 5k iMac when what you have is such a great machine. It's upgradeable, modifiable, and awesomable.

Performance is a very ambiguous thing, your mac pro will have better graphics performance but if what you are doing is CPU vound the iMac will be better. That doesn't take into account drive speeds memory and connection bandwidth and a myriad of other impacts on system speed. You have given no indication of how you use your computer so any advice may well be completely wrong for your use case.
