well your favouring an inferior product is all I can say, Nvidia aren't market leaders anymore.
In terms of quality, all console manufactories now either use ATI or propreitry based products. ATI consistantly beats nvidia in every test, ATIs products are cheaper, hell ATIs products are better quality these days.
Nvidia are only really holding any position in the market due to that attitude in all fairness, but whatever, your money to waste of course
I would recommend seriously looking into performance and quality next time though if you want the best card for your money.
