Radeon - not Radean.
You probably have Radeon 5870, not 5780.
It is not worth the money.
If you have 5770, than you will see solid improvement with 7950.
What about the Nvidia 680 for Mac?
I had a GTX 680. It's a good card and a decent upgrade from what you have. As long as you don't get one that's too weird, it's incredibly easy to flash the PC version into a MAC version.
Is buying a Radean 7950 Mac Edition going to be a big improvement for gaming over my ATI 5780, or is it really not worth the money? Running on a Mac Pro 2012 3.06gig 12 core.
Then - not than.
And it depends - check Barefeats for a multitude of tests. I think OpenCL was vastly improved over the 5870. Apps like Final Cut X heavily use OpenCL. 5870 is still a pretty powerful card, even in these days, though.
OP is interested in games, so i don´t see how is OpenCL relevant here.
that card has had allot of defects reported on here as is screen flicker and heavy artifacting in intensive open cl applications.
I considered that GPU but in the end went with the MVC HD7970. It doesn't (and never did) have the screen flicker issue, it's faster and very good with OpenCL. It's pretty much identical (except for physical form) to the D700 in the nMP. This is a big plus if you are looking for continued driver support from Apple for future OS X releases.
With this, Apple wireless AC/BT, and Apple SSD w/native Trim, upgrades, resets etc... are all pretty much assured to be a fairly smooth process.
Most games use OpenGL right? What is Open CL used for?
For gaming, put a GTX 970 or GTX 980 in your Mac Pro.What do you guys think of the 780 vs. the 680 for gaming.
