I am making a computer, and as my first build, all is ready. But I've heard of the new ddr4 memory and the new skylake cpu's and I'd like to know if it is worth it to future proof by buying ddr4 and skylake cpu's etc... Instead of the usual ddr3, haswell etc..? The fact is that I'm on a budget, and I reached exactly it with my build. I'd also like to know the differences and comparisons between them.

DDR4 is technically much faster than most DDR3 memory (at least in bandwidth, not always in latency), but this has a minor effect on performance for most things. The biggest improvement is when you play games using integrated graphics and even then, Skylake's graphics isn't terrible for integrated, but it isn't great. Skylake is generally not worth the extra cost imo unless you want the option of upgrading to its successor, assuming Intel reuses the socket one more time like they have been doing since Sandy/Ivy Bridge.

Other differences for DDR4 include lower power consumption (though memory still isn't using much, even with DDR3, so this won't do much for the computer overall, except in laptops and things) and higher cost (this will...

Most games are not strongly impacted by memory performance, especially since the 2133 tests also had very loose memory timings, not just lower frequency.

However, since DDR4-2400 and sometimes DDR4-2666 modules are usually the same price as DDR4-2133 modules, there's no reason not to get the faster ones should you go for Skylake.
