When that happens, I wouldn't be surprised if the current generation of DX10 cards aren't in the same boat as our 7950gtx's. So... 2 years of un fettered joy, and one year of researching our next dream machine.
My computer has a 2.4 Ghz P4 processor, thinking of upgrading it to a 3.2Ghz, and I just took delivery of an NVIDIA 7600 video card as well. Needless to say, it runs games pretty well although I don't game much on it.
I'm not a benchmark guy either so as long as I can run things well it doesn't matter much to me, most of my gaming is done on consoles anyway. The difference between both the AGP and PCI-Express version of both cards isn't that much when it comes to performance, at least not yet.
It will be some time before things require a DX10 card as the minimum and a dual core CPU to run. The current $600'ish DX10 video cards will be considered obsolete in a couple of years too so those with recently bought DX9 and DX10 cards will be in the same boat.
Keep in mind that the other 90 something percent of the world has to make the switch and most people aren't ready to get rid of their systems yet, so unless game developers have a real good reason to use DX10 only they will stick to having both DX9 and DX10 versions of their games.
Just like HDTV, it will take some time before it becomes a world standard (it took DVD and CD about 11 years to do that). Besides, you can never be on top of technology and if you keep playing the waiting game you will never buy anything.
Just as soon as the latest comes out they will be announcing the next best thing about a month or so later. Just get the best you can get right now and enjoy it, as long as it runs things the way it's supposed to with satisfactory performance it shouldn't matter.
