How much graphics memory? (brand, power)

Does anyone have any opinions/experiences with newer games and laptop video cards that can answer these questions (beware!: theres alot of them )

1) Is 128 mb Geforce Go 6600 card good for most of the games out today? (Guild Wars, Half Life 2, Counterstrike: Source, etc.)

2) Do the laptops overheat really easily with a 128 mb video card? if so how to prevent?

3) How much of a difference does model/brand make? ie.
128 Geforce Go 6600 or
128 Radeon 9700 Pro or
256 mb Radeon 9700

4) is Asus Z71v good for something like "Guild Wars, or similar games"?

5) If dedicated video memory gets ruined, how easy it is to replace/fix them?

6) Does more memory (ie 256 over 128) cause more overheat?

7)Has anyone ever heard of or had any experiences with "www.cyberpowersystem.com"? I see they have good prices for nice computers, but never hear of them before (i heard from friend).

Thanks for any help!!

 

ok i'll try to answer your ?

1) yes should be able to handle any of todays games no problem.

2)no at least my Dell 9300 doesn't and it has a 6800go in it.

3)the 6600go will be about 2x faster than the ATI 9700 plus the 6600 is Pci express and the 9700 is AGP

4)not sure never used one

5)depends on the notebook

6)not that I have noticed

7)yea I checked them before i got my new notebook, they do have pretty good prices but I couldn't pass up the deal i got.

sorry I couldn't answer all your questions but hope this helped..
