( About your not re-installing XP question..I recently installed this mobo ( DS3L ) using XP Home..my previous mobo was a Via chipset unit..all I did was delete the Via mobo drivers..all of them.. in control panel, went into the registry and deleted all the Via entries that I could find using the search/find function. Shut her down, then installed the DS3L..I had previously downloaded all the latest drivers from the Gigabyte site for the DS3L, on the initial boot up I noted a hard drive light problem that was fixed after the boot sequence..XP did the deed and found all my hardware..when my sys stopped thrashing and was stable..I installed the Gigabyte drivers and all was fine. Go for it. )
I don't see any problem..just have the latest drivers and files for your new mobo of choice ready on your HD and do it. If you are haveing any XP OS issues..then you might reconsider your decision. Mine was running just fine at the end of May..and still is.
