I've got a much different opinion on this. Probably due to the fact that I got in on the chumbo deal where the 6800GTs were essentially $375 a piece. 1) I can now run HL2, Doom3, and many other games I play at 2048x1536 with full details without my system puking on itself. 2) If I decided to say "screw it", I could easily sell a GT for a nice little profit.
As for buying "up to date features" and "next gen cards" with "twice the performance" every year, let's face it, that cannot be done. Anandtech first reviewed the 6800 in April. April! That'll be a year pretty soon and you still have to break your neck (and your wallet) to find 6800s today! I realize it is mostly a problem with PCI-E moreso than AGP, but you get my point. The days of refresh after 6 months and new gen 6 months after that are over.
Oh, but it doesn't stop there. SLI mobo is more expensive and good powerful PSU will also being more expensive as well as buying another card.
$40-50 more for SLI mobo... plus the ability to do a mod on the Ultra and get SLI functionality. This really is moot. As for a PSU, I would say an OCZ Powerstream 520 is sufficient for running SLI. If you look at most people that purchase that PSU, they are NOT doing SLI. Therefore, I will call that point moot as well.
Really, the only thing that costs all that much extra is the 2nd video card. And, yeah, that is a chunk of change. Especially when the benefits seem slim at the moment (i.e. most games now can be maxed out with a single 6800GT), but who knows what the next round of games will require. F.E.A.R., S.T.A.L.K.E.R, Age of Empires 3, etc. They could all bring nice rigs to their knees for all we know. But probably not an SLI setup.
