I have a system built around an A7V and Tbird 750. A friend is thinking of having me build a similar system for him. I am considering purchasing an MSI K7TPro2A + Tbird 1 GHZ for myself. My question - how difficult would it be to remove the A7V 750 Tbird from my current system and insert the K7T Tbird 1 GHZ. Any registry issues ? Thanks for any help.
