Usually not, but there are exceptions. What I’m asking is about how RAM impacts gaming on an APU. You’ll want dual-channel support with the highest frequency possible and very low latency clocks. For instance, a 3200 CL14 kit works best when paired with a high-speed setup—like eight gigabytes of memory—but not because the APU will consume it all. If your RAM is only eight gigabytes, especially while using multiple tabs or browsing, most of it will be used and you’ll run out of space for the APU. The motherboard matters too; it should handle high frequencies and possibly offer more than two slots, which helps if you already have two sticks and want to add more without buying new ones.
You already have two 2GB RAM sticks. Adding half an 8GB RAM (like a 4GB 3200MHz model) would give you more capacity without replacing your current setup. Stick with your older sticks or upgrade to the new one for better performance.
You're getting a bit mixed up here. The first motherboard you have is designed for DDR3 and only has two slots, which means you either keep what you have or replace those two with more capable ones if you want better performance. If you decide to buy another board, it should be an AM4 model. This tells you two key points: your current CPU won't work because it's from a different brand and generation, so you'll need an AMD AM4 CPU; and your existing RAM sticks are DDR3 while the new board supports DDR4—those won't fit together. You also only have two slots for RAM, which is limited. I recommend choosing a board with four slots for future upgrades unless you're certain two slots will suit you. Plus, unless you're sure about the setup, you shouldn't skip getting a new CPU or RAM kit.
Sorry for the confusion, I only read the reply and accidentally joined a discussion about RAM modules myself. I thought you were the person interested in getting an APU, so I suggested buying two DDR4 sticks for dual channel speeds. If your budget allows just RAM, then a G.Skill Trident Z 3200 CL14 16GB kit would be ideal—make sure to check the CL number, as it matters for compatibility. It’s currently the top performance option you can afford.
