how big is the speed gap between ddr3 and ddr4??? I'm building a pc and need to know the speed gap difference between these two ram formats
you guys can check out my planned build here:

As a computer technician and regular PC builder, I'd like to give you some advice.
There is no real speed difference on the RAM form factors, at least not yet. With higher frequency comes higher latency. However, almost any Z170 motherboard (which you should get if you're using Intel and want to keep your future options open) is going to use DDR4. As far as picking RAM, the rule I use is latency/frequency. The lower the number, the better. You should also pay attention to reviews. It's never let me down.
Get a single ~240GB SSD for Windows though. You can install a few programs on it too, but for the most part just use it for Windows. It will make a huge difference. Stick with a SATA one though. The difference in AHCI vs NVMe isn't cost effective. Most people will tell you otherwise, but that's because they don't understand that what really matters is how fast it can read/write SMALL files. NVMe capable drives have lightning fast speeds for giant files, but the difference between reading/writing small files is minimal. Stay away from the brands PNY, Kingston, and SiliconPower. They're known to do bait-and-switches, sending you a drive that uses asynchronous NAND. That will give you about 30-50% less speed.
This one is a good buy.
Your CPU is an
excellent choice. It's got nearly the highest benchmark to price ratio of any consumer CPU. I don't recommend overclocking it right away though. If you do it wrong, you can take a few years off its life. The GPU is amazing too, although I personally would have gone with a 3GB one to save money. It may pay off in the future though.
Unless you plan to RAID0 those hard drives (which I strongly advise against if you don't have a backup drive), you should consider switching to a
single 2TB drive, simply to improve airflow. A cool PC is a faster PC. I can't find how many platters it has (fewer is better, and that's really the only thing that matters besides RPM), but the benchmarks are good. It's also got a 5 year warranty, which is a big improvement over the standard 1-2 year warranty.
On the power supply, you can save yourself some money by getting
a semi-modular one. It's only $60 after a MIR. There's really no point in getting a fully modular one, since you're going to be plugging in those power cables anyway. It will help make up for the cost of a SSD.
Hope you found this helpful
