what in most of your opinion is the best  setup to make Bryce render more quickly?

for me I use an ati 9600, amd xp 2500+ (barton) cpu, and only 2 gig of ram (its the older socket a thing) I know I need to invest and move up..any suggestions for a guy who isn't all that rich?  lol

I am sure ram is one factor for certain

and.. what do you all think of vue.. from what I have read / heard about about vue, Bryce is still better I think
