What the heck are you talking about, no money for a conroe mobo. You can get them <$100 all day. Sure there are $250 boards out there, but if you can live with an 'entry level' board, the conroe chip would MORE than make up for the extra $50 spent on the processor. To me, if you are building a new system from scratch, conroe is the only way to go right now.
The ONLY reason I got a amd, is so i could use my 6800gt AGP card, and I had VERY limited funds... If I had an extra $250 I would have done the E6300 and possibly an entry level 7xxx series pci-e video card. I may be doing that in the near future actually. =)
