Whoa. Right now I would go with nvidia becaue most of ATIs top of the line products are paper launches. As for the all in wonders I dont know much about them since they are of no use to me and I dont think it is worth the money they charge for it. If you can wait a little bit till when an x1800 xt comes out then wait. And no you cant change agp into pci-e. The gt and gto cards have been reported to be able to have their pipelines unlocked so you can look into that. While ATI is great right now nvidia has the lead. ATI is lagging. Not because of poor performance but for poor availability.
