I am no expert when it comes to hardware, but i am good at comparing visual differences when it comes to games ie.anti aliasing, textures etc. I currently have an HP Envy DV6 laptop with an AMD Radeon 7640G graphics card. I was wondering if there was anyway I could install the 6770M into my laptop. Now the Graphics card is kind of big, but is there somewhere I can take it and they could install it to where....it may stick out a little. If not, is there anyway I can get a new graphics card better than the one I already have because I have lots of lagging and FPS drops on some games.
It is possible, but it would take such a high level of skill, and equipment, the cost would be prohibitive.
Probably a factory level, or highly sophisticated, laptop repair shop.
Un-soldering the chip alone would require special equipment.
The only individual that I know of that might be able to do, is Ben Heck, of the Ben Heck show.
He not only has solder re-flow ovens, he makes his own out of toaster ovens. http://revision3.com/tbhs
You could ask him if he would do it for his show, but I suspect, it would be too big a project, for 1 or 2 shows.
