Should upgrading my macbook pro solve my problem?

[billyboar]

I have an early 2011 13inch macbook pro (8gb ram, 128ssd) and I use it for programming. Mostly I run Atom/Sublime with some extra plugins, iterm2 with 4-5 tabs, spotify, google chrome with 10-15 tabs, Skype and Evernote. I want to run a virtualbox running Ubuntu, but my macbook pro fan already runs nonstop and gets too hot to use its builtin keyboard and little bit slower. I'm interested in buying 2015 model. How will 2015 model handle my needs? I'd be interested in only 13 inch model, since I get to carry my laptop here and there.

The power difference between your 2011 and a 2015 machine isn't all that big. You're probably running out of RAM though in normal usage. You machine can take up to 16GB.

When it comes to CPU, the 2015 is about 30 % faster than 2011 when looking at the most powerful models of the two machines, according to Geekbench 64-Bit multicore scores.
You could probably benefit from installing some more RAM.

I would not think the usage you described would normally result in this kind of heat and fan ramp up. Next time it is doing this, launch Activity Monitor and look in the memory tab at the bottom and see what the memory pressure looks like. Also click on the CPU tab and sort by %CPU to see if you have something running amok chewing up CPU cycles.
