I also render to my end product destination and thats mostly for web viewing in which case I would render at either 72dpi or 96 dpi (depending on the intricacies of the textures used) and output to either 800x600 or 1024x768. For printing purposes I then crank up to 150dpi 3000x4500 and this can be very CPU intensive and time consuming. Ive gone for 2 weeks time without the use of the computer while waiting for the final render. Believe me, you can go mad waiting and often tempt the hand of fate when trying to sneak in some on-line multitasking and praying that nothing crashes. 8/
