I think what i will most likely do is wait a while longe3r until the XP64 bit beta is more functional.I'll just keep an eye on it and see where it goes.If everything goes well and they rid some of the complicts and problems then i will definently upgrade.But since the only release so far is the beta i'll wait i actually thought capcom already released a full version because i found an AMD64/MSI mainboard combo which it says comes bundled with Windows XP 64 bit version.I cant see how thats possible considering its still in development.
