Help me be sensible?

'lo all,

Going to start ordering the parts for my new system in 3 weeks time, leaving me 21 days to gather information and make the right decisions on parts.

Going to be a Conroe (of course) .... possibly E6600, but my thinking is increasingly going towards a lower end Conroe CPU, due to all the noises coming out about Penryn. I know no-one knows if Penryn will work in current motherboards, but my gut says it will....and on that basis my thinking is…get a heavily overclockable chip now and upgrade in 12-18months. I know this is a technical gamble, but one that I'm willing to make.

To minimise the risk I want to get one of the very latest motherboards, based on the 'tentative logic' that the newer it is the odds become slightly better that Penryn will work with it when the time comes (again I appreciate however no boards are being specifically designed with this in mind at the moment).

Graphic card for the new system will either be a 8800GTX or a R600 (depending on how good the imminent reviews of the latter are), but no SLI or Crossfire support is required....I’m a one card man  

Onboard sound not needed, especially those 7.1 versions, as I will look to add a Fatality Creative card or something of that ilk, although, like onboard wireless, it seems like a trimming that comes with most new decent boards? (but if it only saves me a few pounds/bucks then I might as well have it I guess)

Other minor considerations - I will also be sticking in a TV Card (not that I believe that changes anything), and I do like the idea of having up to 10 USB 2.0 to play with.

Before offering your advice, remember I have 3 weeks to play with, so if you know of any motherboards ABOUT to be released, keep those in mind too.

You people are a goldmine of information and I now prostrate myself before you in anticipation of your wise council....in other words, thanks very much for any help you can offer
