Could be, though it also depends on what you are doing with it. I know that Cycles doesn’t use ATI cards because of their drivers so everything is done with the CPU. I currently run with an AMD 8350 and haven’t encountered any real performance issues. Though once you pass 600K to 700K polys on a single mesh Blender does start to throw a fit haha.
@: Yeah, I’m excited to see what happens with future updates. Another thing I do like about Blender is that updates are usually between 1 to 3 months apart. I wish Autodesk and Pixologic would do that with their software (though I don’t know how often they update Maya LT).
To the OP, if you are interested in sculpting at all and don’t have much to spend, I would recommend you check out Sculptris. Its free and very easy to use on top of just being another awesome program.
