Bigger GPU memory bus and higher memory clock=higher fps in 1080p & 4k or is it to extent?

It's best that ya forget bandwidth, memory and clocks and just look at the results. Biggest block, fastest rpms don't always bring the biggest and baddest to the finish line first.
Best just look at who wins. Start here and look at the next 18 pages

It depends on the architecture.
NVidia's new Maxwell chips with 128 and 256 bit memory busses do quite well against older chips with 256, 384 and 512 bit busses..
If you are looking at older cards then the bus width was much more important.

Yes to an extent.
If you look at the article Jack posted you will see that the Titan X wins a lot of the benchmarks.
It has a single 384 bit bus.
The 295X2 has 2 512bit busses.
The SLI GTX 970s have 2 256 bit busses. Maxwell based.
For years wider busses meant better performance, but todays newer Maxwell chips do very well with smaller memory busses.

In this article you will see that a GTX 960 128bit bus matches and beats the GTX760 (256 bit bus) and the R 9 285 (256 bit bus).
So you need to look at benchmarks and not theoretical performance based on architecture. A bigger bus (theoretical better performance) does not always mean better performance.
