Hi,
If you find that you are running into problems with the hard drive "thrashing" while you are rendering, which shows that the OS is having to use your hard drive a lot for virtual memory, then you would probably find that more RAM would speed up your render times. That's because TG2 would be able to use more real RAM as opposed to the OS having to swap stuff from RAM to the hard drive and back. More RAM is always good, especially if you're rendering complex scenes. There's no way to quantify the potential benefits of adding more RAM, for example to say "Add 1 GB more and rendering will speed up 50%" or something, it really depends on the scene. I think 1 GB is a good minimum amount, 2 GB is a good amount and at this stage 3 GB is probably a bit much solely considering TG2 ( not that it would hurt ).
Some people mentioned that your CPU is more important that RAM until TG2 is more optimised. In this situation the two aren't really related. Your CPU speed does make the biggest difference, and if you could afford to upgrade your CPU then that would be the most worthwhile optimisation. You wouldn't get the same jump in speed from adding more RAM as you would from upgrading your CPU. That's always going to be the case whether TG2 is optimised or not. However RAM isn't all that expensive and having more is always good.
As TG2 gets more highly optimised you might even see the RAM usage go down, which would mean you could then make more complex scenes with the same amount of memory usage.
