PC_GI :
no thats not the case here. I have personally removed this entire card and applied new thermal paste. it is not soldered to the board. it is just in a PCI slot thats alot like a Ram slot
That's crazy. I wonder if it had to do with the reseller (did you get yours through an e-tailer or through a retailer?)
I know that the 9800m GS is an MXM slot card (Dunno if it's 2.1 or 3.0), so it is interchangable, but in my case is soldered on.
In any case I digress. I've yet to see one under $400 anywhere online, so I wish you the best of luck finding one.
Again, it may be better to e-bay your current laptop and use the difference for a newer one.
($900 [e-bay example, don't know it's real value] + $400 (you would have to spend on the graphics card) = $1300
You'd end up spending a few hundred more for arguably a better proc, more ram, and a card that is at least as good as a 280 GTX.
Not knowing a budget doesn't help, but you again, I agree with everyone else here in that you'll be hard pressed to find a modern MXM style graphics card of decent power that is priced reasonably. I believe that Dell replacements for the 9xxx ATI series are still going for upwards of $80 if that tells you anything.
