Maybe there's more to it than that then. XD
Ah, this is why he's picking the 5850 > 5870:
For those wanting to save a few pennies, ASUS' Voltage Tweak-packing Radeon HD 5850 can raise voltage from 1.088V to 1.4V. That'll increase GPU clock speed from 725MHz to 1,050MHz and memory clock speed from 4,000MHz to 5,200MHz.
Yes, yes, you could probably do the same thing with the program but that was his logic, I assume.Edited by Futan - 9/24/09 at 10:10am
