You dont need something that fast. If your aiming to save money, even something as low as a processor with 1.8-2.0 GH is probably more then enough. If you want something to insure you for awhile, aim for something higher. Another thing to look at is getting a tower. Its simply easier to overclock, and that makes something cheaper a few .1 GHZ faster. Just look into it. ^.^
It'll be good if you can afford a sata HDD running at 7200rpm. There are several on the market. About the rest i agree with the written above.
Other thing is that you specify too little info about the needs and the budget you have for this machine+)
I would take a good, hard look at the Acer offerings. They do appear to offer most bang for the buck. You can even purchase an extended warranty out to 3 years that covers accidents as well for about $175. That's fairly cheap insurance, even though I think they're pretty good to start with. 8)
Since this is a notebook that u will probaly take everywhere and you are willing to spend so much, why not spend on a machine thats powerful and looks killer too. I would suggest buyin a machine from http://www.falcon-nw.com/index.asp just look at their gallery and you will be sold...
No offence but that's money for nothing(except maybe the paintings on the lid of the notebook). I mean, that's a real waste. The good look has improved no machine's performance. Besides, I think both Acer and Fujitsu-Siemens make their machines stylish enough but they don't tax you for that. If you want good looking machine you can look at Acer's Ferrari series. Great look, but you pay almost only for the hardware inside, not for the brand
choose the 770 model for the CPU
2x1GB DDRII 533
make the hdd a 100GB 7200 rpm one
add a TV Tuner
and an Audigy2 ZS
and an 802.11G with bluetooth
and a Logitech G7 cordless mouse(best for gaming)
Sound like a 770$ less than the Dell. I'd say paying less for a better machine is cool enough.
