Why give up part of the market? Seems like a shame to. New ATi graphics boards and chips will come in two flavors -- PCI-E and AGP, so legacy systems will get some of the benefit of newer technology without users having to completely junk their motherboards (or, more accurately, their entire machines...)

[COLOR=#1951B9]"We learned that the X600 and X300 generation or ATI cards won't remain PCI-E only. As we said, Nvidia and ATI donít plan to kill their AGP parts and they have to co-exist at least for some time. "[/COLOR]

[COLOR=#1951B9]"ATI sees the life of AGP lasting for the next 12 to 18 months so has to offer something to users that want a new graphic card but donít want PCI-E platforms. "[/COLOR]
