And you can further optimize your renders by carefully adjusting your render quality settings (AA and sky quality settings in particular).  I just do lots of small tests at different settings to see where the best point of optimization is.  My rule of thumb is to nudge settings up as long as it looks better but if I can't see the difference, there's no point in going beyond.  When comparing, it helps to open both files in an image editor for A/B comparision so you can see the subtle difference in details.
