The first DirectX10 graphics cards were officially released today. This means that basically whatever's currently in your PC is now obsolete. The GeForce 8800GTS and GTX are on sale at a bunch of places now, but they're not cheap.
GTX - $700:
768MB DDR3 clocked at 1.8 GHz
575 MHz core clock
GTS - $500:
640MB DDR3 clocked at 1.6 GHz
500 MHz core clock
Both are capable of 16x full screen anti-aliasing!
It'll be interesting to see how much people can overclock these things. I'm guessing not much, probably more on the GTS though.
Anyone planning on buying one of these? Personally, I'm gonna wait for the ATI card to come out and see what they've got. Rumor has it that the core clock may be 1 GHz or higher!
P.S. - I was kidding when I said throw away your graphics cards. DirectX 10 won't become a standard for a good few more years.
