Right now is a good time to build a very high end AGP based system, as it probably will be the last time you will be able to do so. If you keep a computer a long time (more than 2 years), then I would go for the trusted/stable hardware versus the new kid on the block who has shown signs of teething pains.
I would agree most definitely with watching carefully before jumping into the PCI-e market. Who says 16x is not going to be obsolete next year? They are still selling MOBO's with single 1x PCI-e slots.
However, saying there is "nothing to be gained from it right now" is a little bit of a stretch. If you could find MOBO's that were identical except for the type of video slot (one with a 16x PCI-e slot, one with a AGP 8x slot) and run them side by side, you would see a performance increase. Maybe not huge. But I would bet money it would be there. Problem is, try to find such a MOBO. While AGP is pretty common on the 754 boards, you might find a Socket 754 with a single 16x slot, but they are pretty rare. Most of the 16x stuff is on the Socket 939 boards. I dont know the Intel chip MOBO's that well, so it might be you could find it there.
Basically what I'm saying is, if they want to upgrade to really take advantage of the PCI-e stuff, they have to upgrade MOBO and processor as well. By doing so, they put the entire computer in a whole different ballpark of performance. By default, upgrading to a top of the line PCI-e/SLI setup will boost your performace incredibly because it forces you to upgrade the foundation at the same time. Why spend the money to upgrade to a high end AGP setup? If you are going to spend that money anyway, spend another 15% and go all the way. The prices on AGP are not dropping like I thought they would. If anything, they have gone back up a little from where they were when the 6800 and x800 first came out (although the top cards have come down a bit, but not much).
Bottom line for me is, I'm good enough with my current socket A/AGP8x platform that I can hold off for a year or so before needing to worry that much. But for a guy who has an older PIII or even a AGP4x type board with slower FSB...........for anyone faced with a more immediate need to upgrade, the money wont be significantly more to go PCI-e, he might as well. The performance increases will more than repay the extra money spent.
