i mean can i change anything in windows settings or services etc or i gotta buy new ram and stuff? if there is something that i can change then if u know please tell meCould be the CPU, the RAM or both. Recording gameplay's going to use a lot more resources. That isn't much RAM for both tasks. As for the CPU. That's going to take a lot of CPU power if the task isn't GPU accelerated.
Also those GPU are basically the same performance wise.
