Will Metal work with a Mac Pro 3,1 or would I need a significantly upgraded video card? I'm running the 5770.

Metal on 3,1 working with compatible videocard ( nvidia gtx6xx, gtx7xx, gtx9xx or ati 79xx, R7/R9 XXX )

But currently it's not used by anything. Only GUI uses Metal only on intel integrated videocards.

So I shouldn't concern myself at the moment with upgrading my videocard if I'm not having problems and can update to El Capitan without metal?

What would be a good/economical upgrade from the 5770 that would work with metal?

Noticed this earlier in the year. I know this thread was resurrected from the dead...

Results seem to speak for themselves...

People agree that a used GTX680 flashed myself would be the way to go to keep this 3,1 chugging a bit longer? I've already got 14gb RAM and SSDs keeping pace but the 5770 is showing it's age. Not really ready for an iMac :(. I'm actually pretty pleased with the upgrade from Mavericks to El Capitan it seems to have really given this machine some new life.

What are we looking at here?
Adobe Premiere Pro CC timeline -- one with Metal enabled, the other using Open CL. Metal has some effects not able to be viewed in real-time (the red).

It is the same card as GTX680 yet newer and cheaper, but for exact model nubmer (if you want to flash it) please scroll throug these two threads:

I second this. 680 is a better value. I have a flashed 770 4gb in my 5,1, works with metal.

Guess I'll have to review what the flashing process is to see if it's within my skillset. I feel like my beast baby 3,1 is reaching the end of it's lifespan but am hoping maybe to get another productive year out of it. Probably updating the GPU would be the best bet... not sure if any 3,1 owners have tried out the Sierra patching tool... I'll probably hold way off on that for now.

Many 3,1 owners are on the Sierra without problems (if you upgrade/use WiFi and BT).
You can use the tool, or patch few files yourself. Those are just few text files that lists 3,1 as unsupported model, or don't have 3,1 as supported model. So you just have to dellete/add 3,1 identifier and Board-ID.

Would flashing a card for someone who has never done it before be a big deal?

Well, i have bricked my HD6850 few times and then flashed HD7950 with my eyes closed...
Since the GTX680/770 is easy to flash, i wouldn't worry to much if you read and prepare yourself for it. :)

Cool thanks! Can someone link me to the most straightforward instructions for flashing a GTX680?
Here are my instructions.

That one looks okay to me, but no promises. Most cards will flash, but not all. Some weird ones don't. Basically if it looks like a reference card its probably fine, and this MSI one looks fine. If it is really exotic it may have a problem.

If you want 100% confirmation you can check this thread for exact cards that have flashed fine:

And don't forget there are also 4GB versions of the card:

And does everyone agree that the 680 is probably the most practical gpu to target for an aging 3,1?

I think that depends a lot on what you are trying to accomplish. It's entirely possible that a GPU upgrade will do nothing for you at all.

What are you trying to speed up? What software are you the most concerned about?

Adobe CC, gaming, general OS
Yes it looks like you would benefit, in some but not all cases.
  • Some Adobe CC apps have GPU acceleration and will improve. Some don't use it, so will not improve at all.
  • Gaming will be improved.
  • General OS will not change at all--an SSD would be best for that.

So do you agree that the 680 would be the most practical for my situation? It seems like from a price point the 2GBs 670s are more attainable. Not sure what the difference is between the two.
