I'd say your vid-card is fully up to date. I don't know how much 3DSMax uses the vidcard, but in bryce you won't notice to much difference in OpenGL mode and no difference in renderingspeed. The AMD's 64-bit processors can be faster if the software is optimized for 64-bit processing, unfortunately (but paradoxical enough also logically) bryce is not optimized fo 64-bit processing. So all the extra money spend on a 64-bit processor would be thrown away in terms of brycian renderspeed. Bryce can render with multiple computers at once. If you want to spend $1600 (you mentioned a $1000 vidcard and a fast CPU) you should consider spending it on upgrading your current system with new processor and then build a renderbox with the old parts of your current computer. A renderbox is usually stripped down to the strictly neccesary parts and just capable of running the software and render. You then work on your upgraded machine and do a the rendering with both your updated machine and the render-box with the networkrenderer.
