after conroe and AM2 are released, there is no reason to wait any longer in terms of CPU... some people might still tell you to wait in terms of video card... as the ATI R600 will be "just around the corner" after G80 is released. it is said that it will be a beast and probably tear the G80 to shreads (concerning DX10).. BUT.. it would be too much of a wait as it will probably be released around vista.. which will probably be early 2007... soo wait till conroe/am2/g80 are released then its a good time to make a decision.
