Subsequently, one may also ask, will adding more RAM make my computer faster?

The only thing that additional RAM does is allow your computer to do more things at once, not actually make it faster. So if you normally have a few dozen windows open before you launch your video game, you'll see some speed improvement by upgrading, or you could just close a few apps.

Also, how does increasing RAM improve performance? With more RAM, more of the program instructions can be loaded and there is less need to keep swapping data in and out to the swap file on the hard disk drive. The constant swapping of data slows down the speed at which applications can run, so increasing RAM will increase the speed of operation of the computer.

Herein, is it better to have more RAM or faster RAM?

Faster RAM will give your PC better performance in certain specific benchmarks, but in terms of actual benefit to most users, having more RAM available is almost always better than having faster RAM. Graphics cards include their own memory, so games aren't majorly affected by system RAM speed.

Is upgrading RAM worth it?

If the answer is no, then you need to look into upgrading. If 4GB is just barely enough, upgrade to more comfortably run your programs. If you're not even at 50% RAM usage, upgrading to 8GB would likely be a waste. Upgrading your RAM from 4 to 8GB may hold value depending on your needs.
