need a new heatsink just u remember. the 5870 heatsink would probably the trick.
The 5870 is running on the GTX 260M's heatsink. The Clevo package I didn't take.... but you could add to the surface area of the copper heatsink with added copper plates...

GTX480M heatsink itself already won't fit M15x chasis..
not to mention other problem like BIOS compatibility, new PSU and etc. GTX460M might be sweet. significantly better cannot be conformed yet since your ATi HD5870 is one of the highest-end card. but i bet you will enjoy tweaking the driver again.
if the seller accept trade-in, i do say go for it

Yeah,... true on that. Not sure how big the GTX 480M heatsinks are as I've yet to see proper pics of that GPU. GTX 460M is a confirmed GREEN in terms of working, just acquiring the card via DELL themselves was the issue with regards to warranty and upgrade issues that DELL Malaysia don't comply with as compared to US. So will have to scout the net again to see how much it would cost but then cost over performance over 5870 would probably stop me from getting it. If GTX 470M , that would be a different story as its supposed to perform much faster than the ATI 5870.... and power consumption is the same....

... Lets see how things develop overseas.....
