turion x2 or intel core duo ,help me

I have every flavor of CPU you mentioned and I am not sure where you read the Turion X2 is not a good multitasker, because it is. I watched 3D Mark's "Return to Proxycon" game test and the X2 flows very smoothly, better than the Core Duo, and possibly as well as the Core 2 Duo.

You are correct that the 64 bit OS is going to give you a performance edge. Now this is going to open a whole can of worms from posts that it isn't and I don't know what I am talking about becasue of this and that article, and theory and yada yada yada, but back in the real world where I ran windows XP x64 over a year ago on my Intel 3.6 Ghz desktop and AMD X2 desktop and again in December of '05 when I ran it on my Interceptor notebook... it is noticably faster.

The Core 2 Duo is 64 bit, like the AMD, so depending on your purchase timeframe you can get a C2D from me right now, or wait a while until their official release and get one somewhere else.

I think a 64 bit CPU just makes sense. You also mentioned the power consumption issue of the X2, there I believe that the X2 falls behind the C2D, but I don't think it is to a ridiculous extent. The power consumpion on your notebook will probably be greater from the video card then the CPU.
