Yeah, that's the only problem with the Ion. It's basically the first "batch". If I got an Ion I would probably wait a year or so, when SP worked out all the bugs and problems with it. Plus in about a year, some pretty nice upgrades will be out (hopefully).
B2k5 + a 68/45 Crossfire doesn't sound too bad. Then again if I wait a year for these it could drop about $100. But then I'd want a b2k6
