desktop vs laptop graphics

Ok I am probably going to pull the trigger on a TV for my bedroom this weekend with the Labor Day sales. The question is how to best drive it. I have several choices. My current laptop which is a stop gap at best since it has crap Intel graphics. I still have never been able to figure out why Intel can't fight their way out of the proverbial wet graphics paper bag. That being said. I am considering a new laptop with an A10 APU which will be significantly faster than my current one. I also have a desktop with a 720BE/Xfired 4850s that is sitting idle except for the occasional transcode job. A quick comparison shows the specs of the 4850x2 to be better than the 7870M by a wide margin. I know that does not necessarily translate directly to performance but it is a rough estimate. The last option would be a new build. The question is how will the A10 compare to the 4850x2 and what could I build for the price of a new laptop?

price wise, the cost of a new laptop with always give you a better desktop. Question is, how much are you willing to spend?

And what does the graphics card need to do? If it's not for games, even Intel is adequate by now. The days of Intel Extreme Graphics are long over.

It is going to be for gaming and watching movies. A dedicated gaming laptop is ridiculously expensive. I am curious how an A10 APU will stack up against the Xfired 4850's I already have.

Not even close.

I guess the best way to think about the A10's built in GPU will probably be something like an HD6450.
