i'd just like to express how I think it seems like a good idea to bite the bullet and skip a few months and wait for an upgrade. We already know that pci-e is coming, ddr2, sli, etc. Upgrading now only seems mediocre. How do you justify upgrading to 64bit now? those 754 (yes?) pin athlon chips weren't even around that long were they? and did they even support dual channel?
