Actually you could equate it to installinga new OS... if you formatted a win95 box and installed win2k or xp, you\'d lose your data. If you just performed a windows upgrade, you\'d likely keep your data, but it wouldn\'t be as stable.... enough of me jabbering on about M$....
If you\'re contemplating flashing to Cacko\'s ROM for the 7x0, you\'ll love it... I just got my 760 back from repair and the first thing I did was flash to Cacko\'s 1.17 and applied the 96mb home hack... it\'s the best thing since sliced bread!

How-To Docs area...
good luck!
