Due to needing a new machine, and wife wanting one that works, I picked up a Dell 8100 (core i7-860, 8GB ram, 1TB HDD, ATI 5770) today. It's got Win7 Home Premium, which I've only used a few times at friend's places. I've also got a spare copy of Win7 Pro (tried it on my 05 home office machine, but couldn't score an index - don't know if the ati AIW X800XT messed it up or something else).
Is there a good guide or how-to to set up a new computer? Last time I had a "new" computer was when I built one for the home office in 2005 with XP and then the HTPC that I last installed XP on it in 2005/2006.
