Thanks for the input, I've heard the battery life and boot time is improved with the upgrade to Windows 7 and that's a big plus. Either mod would run me about $100.00 at discounted ebay prices. Any problems with the move from Vista to Win7, and did you use the 'upgrade' version of the OS to keep your files ect intact?
I checked the specs on the Turion X2 TL 68 with those of my TL 62 and the only difference is the .3Ghz speed increase far as I can tell, there could possibly be BIOS issues though, I'm wondering if the extra speed would be noticable at all anyway quite frankly as I never heard of anyone doing a similar thing. Both have the same Cache numbers so no improvement at the back end.
