Yes you will, especially if you go for the ddr ram and 266 bus. Bryce uses processor speed, not video speed so an upgrade in processor works just fine. Money aside, I heard the 1.5g intel chip (if you can stomach intel) uses a 600mhz bus. The 1.33 Tbird athelon is supposed to do that too but there are no MB's out there that support it. A 600mhz FSB has got to render faster than a 266 fsb.
