I did see one difference in the Norwood card. The core is factory overclocked from 250MHz to 400MHz. Which is a pretty hefty overclock. That was the difference in price, plus the ATI was on sale. Which makes sense since the "built by ATI cards" are usually more expensive.
Since the Norwood card is overclocked you will get better performance out of it. And since it was overclocked by the factory you wont have to worry about the warranty be voided as opposed to OC'ing it yourself.
But when I take out the car it sys ATI on it, maybe I shoudl go return it for the 70 dollar one if it's 3rd party company
I'm with Saph, if your happy leave well enough alone.
