For gaming, how big a difference is there between DDR3 and DDR4?

It's been nearly 10 years since I last built a gaming PC, but I figured now is a good time to dive back in and put together a gaming and VR-capable machine. I've decided on everything but the CPU and motherboard. The AMD FX-8350 looks like a great deal but I'm not sure how future proof it's going to be. As for Intel's new Skylake, the best my budget will allow is the i5 6500 or 6600. For my purposes I assume the 8350 and i5 would be about equal so it comes down to is memory performance. I know DDR4 has greater bandwidth and DDR3 generally has faster timings/lower latency, but what about real world performance? Is there a performance gap and if so, how large?

The difference between DDR3 and DDR4 is negligible when it comes to actual real world performance in gaming. I'd recommend the i5 because it performs better than the 8350 when it comes to gaming, this is because games generally use 2-4 cores and the i5 has much better per core performance. The i5 also consumes much less power and has integrated graphics if ever you have a problem with your graphics card. If you are planning to build a VR-ready system it'd be wise to wait for the full new graphics card lineups from AMD and Nvidia.

That's my plan, though some of the sales on 390s has been tempting.

Thanks for the help.

Don't confuse the lower numbers in timing for faster speeds like I did. I would see speeds like 9 9 vs 13 13 and thought, of course the 9s are faster. But I did a Google of timings and that's not the case anymore. I can't remember what I searched and what I found, but it made me realize I had been buying the wrong ram for a while. I just did a search and found something on crucial's site that explains a bit.
