You have to transition to 64-bit at some point. I imagine that this is the innitial first step and in 2-3 years time we will see the full benefit of the move to 64-bit.
In short, I would rather have a more future proof phone so I don't see it as a gimmick.
The extra registers could provide a small gain, maybe 2-3% for some tasks and 4-5% for other tasks, on the iPhone. I wouldn't expect much more than that. The applications that would benefit most from the extra registers aren't the type of applications that you typically find on a phone.As mentioned in an excellent article from extremtech

Couple of things:
1) Classic example of a headline not matching the content. In the first paragraph they admit there are performance benefits to moving to ARMv8. There's also going to be performance improvements from the design of the chip itself.
2) The argument is based around there being no benefit if you're the first person that moves because you need apps to be 64 bit, not just the OS. This is correct... but incredibly short sighted. Delivering the potential to run 64 bit apps in conjunction with a massive redesign of iOS is going to encourage a lot of developers to take advantage of that functionality. It's the perfect time to start making this switch and - here's the important thing - it's a switch that every single mobile manufacturer is going to have to make. Apple are now ahead of the game and within... what, two years or so every iOS device they sell will be 64 bit capable.
It's the equivalent of saying that the Mac moving to Intel was just marketing. In the beginning, yes for the most part it was, but the long term benefits were instantly obvious. Same thing with iOS going 64 bit. Though that said the big benefit is likely to be the iPad rather than the iPhone. It's going to be fascinating to see what the A7X can do and, more importantly perhaps, if Apple introduce new software to take advantage of that power...
How about for gaming can I live without a 64bit processor until the 6 comes out?
I dont agree, the article mentions the longer term benefits you allude to but emphasises that we wont notice much of a difference in the shorter term. The iPhone 5s is the only iPhone with a 64bit chip, compared with the installed base of 32bit ios devices, it is an insignificant fraction of the total. That will of course change in time as new 64bit devices are rolled out. If I were a developer, right now I would feel no urgency to create a 64bit version of my app, unless, of course, it is a simple push button exercise to convert.
