> in some it may read sd ram or ddr ram or sd-ddr ram.
LOL.. yeah, I understand your confusion. There is SDRAM and DDR SDRAM. The latter is often called DDR Ram (DDR=double data rate), but it is also a form of SDRAM. duh.. still not clear is it.. Either way P3's will only come with SDRAM, which is fine, since they cant really benefit from the faster DDR. P4's would come with either SDRAM or DDR (SD)RAM. Go for DDR if you decide on a P4
>i have always been told the athlons perform significantly >better then intel chipsets
Yeah, no, well.. lets hope this doesnt turn into a flamewar, lets just say Athlons are faster than P4s given the same clock speed (eg a 1400 Mhz Athlon is considerably faster than a 1400 Mhz P4). The same can not be said of P3's. Athlons and P3s perform about on par at the same clock. Now the tricky thing is, all new Athlons (the XP's) are labeled with a PR rating, not their frequency (eg Athlon XP 1600+). The PR number is roughly comparable to a P4 at that frequency.
Now performance is not only determined by the cpu, far from in fact. Memory, chipsets, harddisks, videocard can make a much bigger difference, depending on your application. If you want to play 3D games, you'r in for a disappointment. Laptops are not well suited for games, regardless of which cpu you get. If you want (limited) ability to play games, get a laptop with a Geforce2go videocard, and even then it will be a far cry from a standard desktop in gaming performance.
Before I go on: perhaps you'd better tell us what you will be using the laptop for, and what matters most to you: performance (on what apps ?), battery life, portability, features,price, .. ?
