I would suggest you go for the 2gb ram and 512mb vcard. It has more performance. 2gb can run Vista and windows 7, while 128mb vcard you'll have trouble on running on these current systems.
128mb vcard is not worth it for a 3gb RAM nowadays. unless its a ddr3 and supports cuda and other nvidia or ati stuff, which is impossible on today's tech.
Also, if need be, you can upgrade the RAM from a 2GB to more. It's harder to upgrade a GPU, and more expensive as well.
normally i would say the 512mb but it depends on the price and quality
No, you can't. Laptops have its own ports. If you want to upgrade your laptop video card, you need to make sure that your laptop has proper ports (mini PCI-E). And then get a video card which will fit that port.
you need to replace your video card, if its got 128mb with intellr built in (integrated tech.) then part of your card is burned out, i would suggest a card with atleast 512mb of onboard mem.
the 8400 is the better card
System Requirements 512MB System RAM 2.0 GHz processor 128MB video card 8x DVD-ROM drive 4.6 GB Hard disk space
The Alienware laptop with those feature is about $250.
Contains a 512MB GDDR3
you can buy from a PC shop it's that simple.
SEEK 128mb Video cards on EBAY :D
For newer systems running Vista and the latest extreme games, it is required to have a minimum of 256MB of video memory. I suggest staying ahead of the game and treating yourself to better performance and graphics with 512MB of video memory.
most likely, yes
That depends. What video out options does your laptop have?
