look im gonna be blunt if you want do anything related to maya get a proper gpu otherwise your still just pissing money away.
took Computer Animation at fullsail and ive done 3D modeling and rendering for the last 6 + years as a hobby, in the end nothing has worked as well as a Firepro or Quadro card,
Maya with ANY RADEON GPU PERIOD will have stuttering and further issues i waited over a year for AMD to simply release a driver to fix the 2-5 second dely when selecting verticies or single UV points select more than one lag increased nearly linearly. GeForce cards work a little bit better but in the end they still take a huge back seat compared to Quadro or Firepro.
and those cards arent that expensive

ill quote myself from my own review.
"We had zero issues in all versions of Autodesk Maya that we used for testing this past month. It was also easy to see an improvement in work flow as the time to get a project moving and getting certain aspects done was easier and faster due to how much more responsive the FirePro W5000 was in comparison to the Radeon HD 7970. That said, up until a few months ago the Radeon HD 7970 we use as the regular GPU in this system was slow and cumbersome with extremely bad performance. Driver revisions have corrected this issue to an extent for the Radeon GPU, but performance is still far below that of the FirePro solution, which really shows how much drivers and support can improve performance and a person’s workflow. The change when unwrapping UVs for texturing for example was just far smoother on the FirePro with the selection of UVs having no noticeable lag compared to the Radeons."
"One thing we do have to mention however is that after exporting our mesh from Autodesk Maya 2012 and bringing it into Mudbox for sculpting out normal maps, we noticed that on the Radeon HD 7970 ambient occlusion did not function as intended in the viewport, but this would be considered a minor issue. The said, the FirePro W5000 on the other hand had no issues rendering ambient occlusion in the viewport. Other than the extra viewport render options functioning better on the FirePro W5000, both cards performed nearly identically when it came to sculpting a high-res mesh for normal map generation. All in all, our experience with the AMD FirePro W5000 was a positive one, with it performing admirably in all tests."
