What is better AMD graphic or Intel?

It depends on what you want to do. For gaming an Intel will work better as of 1/1/14, most games only use 4 core technology. Intel benefits from this because it has only 4 cores.

For video editing I'd go AMD, it runs a bit hot, but a third party cooling solution should do the trick, lots of programs take advantage of 8 cores, it's also good for server hosting, but Xeons are better for hosting servers.

Overall I'd go AMD for overall value, but if money isn't a problem go Intel.
