Best price I can find on the 850XT PE is $396 and thats using pricegrabber.com. Didnt see the 7900GS listed anywhere using pricegrabber.com. So, I'm thinking that when it comes to the question of 850XT PE or the 7900GS one should choose the cheapest price they can find it at.
There is also the question of supply. I'm wondering if the AGP supply will dry up totally. Logic would say it will as PCIe becomes more mainstream. So far ATI isnt showing any attention to adding newer cards to the AGP spectrum but nVidia has with the 7900GS. As time goes on those people wanting to stay with AGP (and there are many that do it seems) might have to look more towards nVidia than ATI. It'll be interesting wether there will be any further competition between ATI and nVidia in the AGP market. I kinda think nVidia made the 7900GS not only to support its AGP consumers but to also tweak ATI's nose.
