Episode 896

Casey from Clovis, CA

Casey loves gaming, but consoles are slow behind the times. Leo says that console games have stagnated over the last 10 years, while PCs have leapfrogged into better graphics and faster processors.

Casey uses his PC for gaming, but he's getting a lot of lag. He's wondering if upgrading his graphics card would improve the performance. Leo says he could upgrade the graphics, but if his CPU isn't fast enough, it will still perform slow. They really work together.
