I've had very good results with PTM7950 phase change material on my CPU, which has not been delidded. I expect it would work even better on a GPU, which typically doesn't have a lid.
(Note that PTM7950 is somewhat difficult to apply, since it comes in a pad-like form that is both sticky and brittle. If you decide to try it, I recommend refrigerating it first, and being careful and patient when applying. I feel it was worth the effort.)
- Really interested in trying PTM on my graphics card, but it's still too expensive. You need several sheets to cool all the components and Thermal Grizzly is the only brand I can get a hold of.
  It's cool (hehe) that it's even available at regular computer retailers though.
  
  How about using one sheet for the GPU itself, and less expensive thermal pads for the memory chips and/or voltage regulators? I think AIB designers often use this approach.
  
  Yeah, I realize now that I'd have to do that anyway, as PTM pads are not available in those thicknesses (if the material even works well at those thicknesses).
  What I should do is get some thermal putty to replace the pads, so I don't have to bother with getting and cutting the right size of pads.
  I also found a PTM pad from Cooler Master on the market called Cryonamics. But it seems like a very new product. I can find no one even as much as mentioning it online. It's half the price of the Thermal Grizzly so I'm tempted to try it.
  
  I read somewhere that Thermalright's Helios line includes pads equivalent to PTM7950. (I don't know if it's Helios V1, V2, or both.) Maybe they're worth a look?
