An add-in PCI-E card might be a usable solution for a laptop, but why should I have to pay more for an additional peripheral when I already bought a laptop with an HD-capable GPU inside?
Once upon a time when you bought a PC (think Apple II or IBM PC) it came with a technical reference manual that not only described how everything worked, but even gave the assembly source code for the operating firmware. (OK, the IBM PC Tech Ref Manual didn't come with source code, but it still gave you full docs on how to program all of the hardware.)
We've come a long way since then, but when did it become acceptable to pay hundreds to thousands of dollars for hardware and not receive full specs for how to use it? Digital rights be damned, consumer rights have been totally trampled.
AMD, Intel and Nvidia need to step up and tell Hollywood to f#ck off and quit trying to dictate what kind of hardware they can or cannot build. With all the reliance on digital effects these days, Hollywood needs to watch its step. The computer industry can survive without the movie industry, but not the other way round.
