Is memory on ATI Radeon HD 5750 1024 MB upgradeable?

I have a mid-2010 27" iMac with an ATI Radeon HD 5750 1024 MB graphics board. I have just upgraded to El Capitan and screen redrawing has become pathetic. Then I found that Photoshop CC was telling me that certain functions had been disabled because I had less than 512MB of graphics memory. So I presume that one of the memory chips on the graphics board is dead. I know some memory is soldered in. Is this the case here or can the memory be replaced?

OS X El Capitan (10.11), 2 GB RAM, Epson printer & Scanner (

The graphics card can be replaced if it is defective; its' virtual memory cannot be upgraded. Here are the specs for your model (I believe):

FWIW, your profile shows that you are running on only 2 GB RAM? If that is correct, you should very seriously consider installing more RAM.

Thanks for your response. Sorry, my profile was carelessly updated and the RAM shown there related to an earlier machine. In fact I have 8 GB of RAM on the current iMac. I guess I have to try to decide whether the expense of a new graphics card is worth it, given the machine is now 5 years old.
