Compared to tested Toshiba Satellite A300D-125:
http://www.insidehw.com/Reviews/Notebooks/Toshiba-Satellite-A300D-125.html
A305 has Intel Core2Duo CPU at 2.26Ghz - not that much faster than Turion at 2GHz
A305 has 4GB ram against 2GB ram that has A300D - more is better
A305 has bigger but not faster hard disk
A300D-125 has a price tag around 750 EUR
A305-s6864 has price tag around 1.150 $
A300D is model for European market and A305 for USA.
Everything else pretty much the same. Monitor, graphics card, optical device etc. They look the same and have same speakers and design.
Bottom Line: A305D-S6864 is a faster version of A300D-125!
ps. If you don't mind lack of DVI/HDMI monitor connector and hard drive that has 5200rpm than you know what to do

Bear in mind that there are many notebooks in that price range and class and don't hesitate to ask additional questions.
