Ok, for bryce, you do not need a great video card if you are just using the machine as a render whore. For the Processor (even though I love AMD's) Pentium 4's own render times... So anything P4 is good. Now, you can either set up a multiproc machine with 2 gigs, or a few single proc machines with a gig each, then use bryce lightening. As always, you don't need fancy features when rendering, you need raw power. IE the higher the actual clock speed of the processor the faster it will render. Even though in games an athlon 3000+ will beat a pentium 4 3.06 ghz... It only actually has 2.16 ghz, and will fall far behind in the rendering industry. (for nearly the same price). Just my 2 cents. Hope it helped.
