Athlon 64's are both 32 and 64 bit ready- so my WinXP runs like a champ now with Vue 5, compared to my older P-III's. AMD's internal processing is much more efficient already than Intel's... And when Microsoft releases it's 64 bit OS, my machine is READY. 32 Bit chips will NOT run it. Your PC Chip and OS have a major impact on how your software runs. E-on could very well be running a test-bed of Vue Infinite on MS's 64 Bit OS because the BETA has been out already for a very LONG TIME. You can get it now, if you like- but there aren't a lot of drivers officially ready yet- but that's why there has been a long BETA- to get most of the major players on-board and getting their software and hardware ready to support it. This coming FALL PC Selling Season will see the 64 Bit OS as the new "BIG THING" to get. And E-on will likely have a 64 bit Vue Infinite release ready to show at trade shows during this Fall Sales-Trade Show season...
