hi all new mac user graphics question

hi everyone ive just bought myself a 1.5ghz 15 inch powerbook g4 it has 2gb of ram installed and has the ATI Mobility Radeon 9700 with 64MB of DDR SDRAM graphics card.

my question is this graphics card any good? im not reaally up on my graphics cards but in terms of reviews, make, speed etc? i do play games occasionally, and do appreciate good graphics.

i have had a quick look on the net and found some cards at 256mb? will these be a big improvement over my my 64mb one?

and also ive only got a max of £50, now ive seen you can get a 256mb one for that price but the question is will it be any good or would it just be better keeping my exsisting card?

and sorry one more question if i do buy a new card can i slot it into the One PC Card/CardBus slot supporting one Type I or Type II card

cheers guys!

 

oh right i had no idea the graphics card couldnt be upgraded. No big worries though my main use for it is music.

and obviously the whole powerbook/macbook thing is down to personal opinion

thanks

oh actually is there any thing i can do to get more performance out of it? or is just the case of keeping drivers updated etc?

 

im from the uk so macbook pros are still roughly over a grand here roughly $2300.so too much for me to spend

 

only playing old games really like medal of honor, so nothing really taxing. would a game such as this be ok to run on?
