thank you CBeckstrand! is it right to say that to upgrade only the memory for now, until i have me too an athlon will be sufficient? :) :) also when you had your k6 233, did you experiment more bugs due to the fact that your system was slower than the system requirement, because we heard carrara has many bugs that were in part corrected by the patch. what do you mean by very slow, slow like bryce, ( it take 6 hour to render a scene whit my computer) me i wanted to buy carrara because they say it is quicker than bryce. we do not know what kind of graphic card you had, because the graphic memory and 3d accelerator can make all the difference. another point: recently i try the do of strata studio pro, (the main compitor of carrara) and the rendering was very fast, like 20 time faster than bryce. i also tryed many ather 3d software and i notice that the rapidity of the rendering is not only proportional to the power of the computer but also dependent upon the power of the software engine, and it's capability of managing opengl and 3d acceleration,and many other variables. So can you develop on the kind af graphic card you had, and if you experiment(ed) bugs whith carrara? thank you:)
