Laptops and their video cards?

[Oblivion121]

I bought a new inspiron E1505 laptop a few days ago, it has the radeon x1400 hypermemory on it. But i came across some info that says they are the native pciE cards, of course not like desktop slots, but still PCIE slots, if this is true, couldnt i take apart my laptop and throw in another pcie laptop card....for say a Go 6800? or maybe somethin a little better than an x1400? or is it an integrated PCIE slot? I wanna know if it is an expandable port to what more than dell offers since they only offer the 7300 turbocache, and the x1400 hypermemory. And I know neither of them will suffice for the use of this laptop, This laptop would be used to play Wow, Quake 4, Doom 3, and more stuff in that genre. Ive got the 667Mhz ram and the 2.0ghz core duo at 667 fsb with 4m Cache so i know i wont be cpu bottlenecked.....Atleast for a laptop gpu. But I would like to know if I can throw in a new video card for it because i have these cards i would like to try in it.

Go 6600
Go FX 5200
Go 6800
Go 7800 Gtx.

Im not 100 percent sure, but I don't think you can do that. The graphics are part of the montherboard, but tied into a PCI-E pipe somehow.

I have heard that sometimes you can change the graphics card on a laptop, however it is not easy to do. Sometimes the graphics chipset may be on the motherboard. If thats the case, then you can't just change it.
