Received my new machine's components today but I'm still unsure about busting open the seal on Vista 64. I've ran XP Pro for many years without ever having to install a manufacturer's driver (less graphics card and modem). The XP install is also absolutely rock-solid, fast and virtually flawless - I've never had a hint of trouble . Is Vista just as capable or am I about to enter the nightmare zone? 
My DSL modem is old but still functional - there are no drivers for Vista on the manufacturer's site. Will it still work?
I need 4Gb RAM+ so should I just RMA it and get XP Pro 64 instead?

Cheers.
