I was wondering what was a better processor for a laptop, the AMD Athlon 64 4000+ 2.6Ghz or an Intel Core Duo T2300 1.66Ghz. I would like to (as much as I can with what I can afford) play some games on this, or run random fractal generator programs on here.

Also, I was wondering which was a better graphics card, the ATI Mobility Radeon X600 or the ATI Mobility Radeon X1600.

The reason I'm wondering is that I'm about to buy a laptop, and I don't know which one is better. THANKS!
