In part listing it showed that you had a Western Digital 5400 rpm drive and a Seagate 7200 rpm drive both were 1TB, none of them SSD both HDD so that is why I questioned that is because on a new build when you buy parts you usually want to stick with pairing of like speed drives vs mixing. You dont have any SSD's listed and a 1TB SSD would be EXPENSIVE if you had one listed. I mentioned RAID as for if you ever wanted to set up RAID for protection of data or the benefit of faster performance that going with 2 like spec drives preferably from the same make/model is suggested.
More on RAID here to learn more about it:
https://en.wikipedia.org/wiki/RAIDOk on the WD as a gift... I wouldnt put your OS on this drive, I would just use the WD for the additional 1TB storage capacity. If not intending to ever use RAID then you will have no problems with 2 drives of different speed spec. For best performance use the 7200 rpm seagate for your OS and Games for fastest load times.
If your looking for maximum performance you might also see a speed benefit of your computer if you once system is built, direct it to use the 5400rpm 1TB WD drive for swap space for Virtual Memory since that drive would be idle and ready to assist, while the 1TB Seagate would be busy with serving up files to RAM for the OS and Games and so having the Read/Write process handled by a drive other than the Seagate could show a performance gain in some gaming situations for example with large map files constantly being loaded as your moving around in a game, and this way the Seagates full performance is going to the OS and Games and the WD is acting like a drive for extra data storage and virtual memory swap space.
More on Virtual Memory Here:
https://en.wikipedia.org/wiki/Virtual_memoryOn one of my systems I have created a smaller partition just for virtual memory swap space and this has an additional small performance gain vs having your swap space scattered across a drive, to keep its allocated space to the best performing access timed part of the hard drive.

But if your looking for maximum performance there are tricks you can do to get the best performance that you can out of the hardware combination. Im the type of guy who will spend an hour working on something for a 3% performance gain and then look for other methods to squeeze out more, but for some a 3% performance gain isnt worth the time to configure for it.
3% by the way measured by a system benchmark and 3% is just about not noticeable to a user.
But at times my system is being used to crunch data unattended and so a 3% gain makes it end a video conversion from a 25GB file down to a 1GB file 3% faster. So if it takes 100 minutes before to do the conversion of the last gaming party recording, it now might take just 97 minutes. Still the system is running full tilt for that period of 97 minutes, but faster than taking 100 minutes. Overclocking is another method of gaining performance and I had done that as well, but extreme care is needed to be sure you dont cook components due to the excess heat as well as you might be making a faster computer at that point, but now its requiring additional power to drive the system that much faster and so it can become a faster computer but power hungry computer as well as act like a space heater in a room.
With that Core i7, you should be good for the next 5 years or so without having to overclock. It all depends on what your processing needs are.
