You may want to use part of that tax return to also upgrade computer. I switched from 1.8P4 w/512meg mem and gobs of harddisk to 2.8P4 w/1g mem and more gobs of harddisk. The actual opening of the program - still slow; but once I begin production rendering - it is as fast as if I was using poser4 render and I set buckets to 5 and raytrace to 6 for detail. I am not happy with all features as all features still aren't working properly but for rendering and setting materials, and hair - is worth upgrade.
