Need Advice regarding fz4000

Hi guys,
Below is the list of what I will be getting for 2000$. Is there anything I should be worried about or know. also should i just get the 2gb ram and upgrade to 4 gb after and would it be cheaper. And is there any other laptop that would be a better buy. Any help would be great.
thanks

It is very easy to upgrade RAM, so yeah, I recommend you to drop 4gb RAM, and I would spend money on more HDD space instead. Also, do you really need features of Vista Ultimate? T9300 might be bit of overkill unless you plan to do lots of media-related tasks, as well. Finally, extended battery will stick out, so it can hurt portability - although, obviously, it helps with battery life.

About other choices - well, it depends on what you want to use your laptop for. I have been using FZ for 6 months and am happy with it, but, say, if you need gaming laptops, there are better choices available.

 

I have FZ21M with 4gb ram(I hope sony provide x64 drivers in the future) and cost 20 euro from 80 in greece.Selling the old 2x1 gb for 60 euro.But the big improvement and i mean that is this. http://www.seagate.com/ww/v/index.j...5a5e3110VgnVCM100000f5ee0a0aRCRD&locale=en-US
My score in vista.
Disk data tranfer goes from 4.9 to 5.4
The memory stays at 4.8
The spare hard disk i put it on external case usb for 15 euro

 

What other choices do i have for gaming laptops in that price range. I am new at this. any help would be appreciated it
