I bought an M17x and i wanted to upgrade the graphics card(currently nvidia geforce 9400m) but i cant find anywhere that sells the geforce gtx 480m. I was also curious as to whether it would even be compatible.
I can find it for a desktop, but not the 480m.
Any help is appreciated.

The M17x should already have a GPU besides the 9400m installed.

go into the BIOS and under ght graphics settings, make sure the integrated, and hybrid graphics are disabled, then reboot.

depending on the config, you should have either a NVIDIA 260, or 280 GPU or a ATI 4870 CPU.

The 9400 GPU is the one that runs by default if your running on battery to prolong the battery life.

But you have to manaully switch the GPU back to the other GPU

I looked it up and i can enable discreet graphics which enables my geforce 260m, but it totally screws up the screen. The screen gets majorly pixely and goes into full on seizure mode.
How would i fix that?

Re-installing the GPU driver first, that is what I would do.

you should set both GPUs to disable in IOS, this will enable the 260 GPUs by Default.

I did. The screen is all discolored and Pixely. and flashes wildly depending on what is on the screen. The only thing that i can even see that could be wrong is in the devices page it shows that coprocessor is not enabled because a driver could not be found. would that even affect anything?

not really but do install the chipset drivers

and for now I would install the Dell graphic drivers as well.

If you still can't get the graphics to work properly on the 260m GPUs I would suggest a fresh OS install, with a format on the hard drive then load the Chipset drivers first (2 of them RICOH, and NVIDIA)

then load Audio, and any others you need.....with the Control Center and OSD drivers last

Forgot to ask What OS are you using ?

Did you buy this system off of someone (second hand?) like ebay? If so, I would put dollars to doughnuts that your 260M is fried and they just disabled it hoping you would not notice. If this is the case, then you need to do a paypal dispute ASAP! I may be jumping the gun, but don't want you to loose your $$ D.

It was fried. i talked to the seller (it was ebay lol) and he had just gotten it from a dell outlet store and had never turned it on. (evidently dell doesnt refurbish quite as well as should be expected) the warranty still has the full year on it (minus a few weeks now) and dell has already shipped the parts to fix it. Thanks for all your help guys.

Glad it worked out for you, those are pretty expensive cards to replace
