I am looking for a good athlon64 laptop...i had the emachine laptop for about a week, but after replacing 3 of them for bad screens i've decided to look elsewhere. I was looking at hypersonic pc, but i saw that cyperbower notebook http://www.cyberpowersystem.com/high...648000.asp?v=d is cheaper. the only drawback is that it only comes w/ ddr333 memory instead of ddr400, and i read that it is picky w/ memory so upgrading mem might be difficult and expensive. is the performance hit that large for the slower mem? what do you guys think I should do. I'll be using the notebook for video encoding and gaming. is it worth the extra money for the hypersonic pc or should i just buy the cyperpower and upgrade mem later?
