It’s unlikely that a $300 PC will deliver satisfying performance and a stress-free gaming experience. While you could wait for discounts on last-gen CPUs and GPUs to put together a decent gaming PC on the cheap, that would take some time. In addition, you would likely have to settle for low storage and RAM, reducing your multitasking capabilities. However, a $300 PC would still be viable for older titles or even some modern games on the lowest settings.
