Mobility HD4570m replacement

[Lex_60]

Hi Folks,
I have an Acer Aspire AZ5610 and want to upgrade the graphics card but can't find where I can purchase the AMD Mobility Radeon HD 6990M.

Any Suggestions? I'm assuming the dimensions of the card willl be similar

Thanks for your help/suggestions

You can't upgrade M-class graphics cards. You're stuck with what you have.

Update:
The real reason was that I'd recently bought Diablo III and the graphics were really glitchy. On loading the program had forced me into updating the driver so I had the most upto date driver.
On delving into Tom's excellent review on D3 I read that Catalyst 12.4 wasn't supported because of glitchy graphics with certain series... So I rolled back the driver and... Super graphics - it can run at 1200x640 (think that's it ) with full detail levels cranked up and no glitches. At 1920x1028 it's very smooth, ultra detailed and unfortunately in slo-mo!

I will probably end up buying a new PC, but for the moment this is pretty good

Btw, thanks for your reply DTS, I wasn't aware they weren't upgradable - not had too much experience with fiddling around with mobile cards. Prefer desktops myself.
