I did it....but then again i was in a much different position than you. I didnt have a socket 754 or 939 cpu to begin with, so i would have to buy that plus a new mobo with a budget of $300. Easy as this seems, my 6800ultra had died on me so i couldnt just buy a new cpu+agp/pci-e mobo. I would have to replace the vid card as well, but i wouldnt settle for anything less than the performance of my previous 6800ultra. At that time a 3200+ with a mobo was around $200 cash and the best vid card i could buy wouldnt outperform previous 6800ultra. So i thought about it and knowing conroe is right around the corner, i decided to get a 7800gs co for $260AR, and overclock the crap out of it to hold me over another yr or more. So all in all i got the performance gains i wanted, which is around 10-15fps in most games after overclock, even 20+ in SM3.0 games over the ultra. I also got a quiet cooler running card, that had all the 7 series purevideo enhancements, and newer driver support plus i could sit and watch how AM2 and conroe played out. Im still extremely happy about my decision, and wouldnt look back for a second. For you just get a s754 motherboard with pci-e and get a 7900gt or an x1800xt 256mb and you'll be much better off.
