Joe, I have to mention since we have relatively similar systems and I just lost my DI virginity this past weekend (though I cant say I was terribly succesful), thats its an awesome experience. There is LOADS of advice already posted in our benching section that will help you out, definately take a look around or search first.
Brolloks experience going cold (I think its a sticky in the benching section) gives you some great advice and like IMOG and Hokie said, if you do it live, the ones that know will watch and help like they have done for me. FWIW, here is what I learned in my session from saturday...
*Preload all OS's (I did XP32 and V32), drivers, and benchmarks (I did this, nobody wants to watch you setup IMHO)
*Have your camera view on your setup and a monitor thats readable, otherwise, like I feel mine was, watching it sucks for others.
*Use a microphone so you can communicate with the viewers who are helping. Between having to shovel snow (DI), I had to reply via typing and that just made the process more stressful to me (My son is in the next room so I really couldnt without waking him, go figure Im a loud mouth
).
*Just pick a couple of benchmarks, 2D your first time. That way you can get used to the benches, and the tweaks and knock out some solid scores.
*Be more prepared than I was for borked OS's. Meaning have an image of your setup benching OS (which should be super stripped down) in case your bork them. It takes just 10 minutes to load my XP and wish I would have had my optical handy so I could have continued.
Im not close to being an expert, but I think those little tid bits will help with destressing and making it a more pleasureable and effective (for boints) experience.
This weekend I think Im doing some 3d stuff (not 06 and vantage) with the 470 and an i5 550 I just bought.
GL to you man...
