Quote - I know that the nvidia ones are limited to about 64 on the 5 series, and currently 256 on the new 6 series. But wondered if AMD cards suffered the same limitations..

I am seriously considering getting a saphire 7970 vapor X 6gb(due to the amazing work that Dade is doing in integrating SLG3 into Lux), but if there is a texture limit then there may not be any point.

The limitations are imposed by the small amount of ram that GPUs have, usually 1GB or 2GB. When a program like SLG or Octane use the GPU exclusively the GPU RAM is used for both the geometry and the texture and texture take a lot of RAM very quickly. Having said so, the new SLG3 is improving the texture management quite a bit.

Anyway, I am partial to AMD GPUs as well. I don't know the model that you quoted but my 5870 works very well.

Cheers.
