I switched out my Cedar for this Cape Verde GPU (Radeon HD 7770 ). It's relatively inexpensive and low wattage.

I just installed an AMD Radeon 7800 yesterday and when I turned it on, two additional projects tried to run, but then it immediately returned errors. It tried two more and got errors for those two, and on down the list. I tried restarting the computer and tried turning it on again, same result. I guess this one doesn't work either.

Added: Apparently it was trying to take two projects because of a second ATI (Radeon 4650) card which is on the bad list, but disabling the secondary card did not stop the errors. I just got one at a time instead of two at a time. I did restart with the card disabled.

I'm not a huge techie, so I'll just leave GPU processing disabled for now. As such, I'm not 100% sure that it's the card and not something I'm doing.

Was that error not indicating the ATI SDK kit needed installing?

There's more cards that for one user just plain fail and for another work. Techs indicate if even ~5-10% [some very low percent] is good, the card in question is not blacklisted, which means one having a high success rate, and other low or none. At least other visitors of this thread will now know to not have high expectations if their system contains one of these.

thanks

@ibsteve2u: You can remotely log in to a machine running GPU work using a Virtual Network Connection (VNC). I successfully use TightVNC. UltraVNC is another freebie.
VNC seems to copy the actual console (GPU) memory, while RDP may implement a virtual screen in main memory.

@Sekerob: "Was that error not indicating the ATI SDK kit needed installing?" The 9600 is an Nvidia chip, so I assume you mean the Nvidia driver.

My GTX 560 ti 448 core will not work either...
