You can't make your computer run any more faster with an AMD E1-2100 APU. In fact, I have an old laptop that's a decade old running an Intel Core2 Duo T5550 (3GB RAM, Windows 8 Pro), which is almost twice as fast compared to your APU, and I can barely watch a 1080p60fps YouTube video without multitasking, so I can't imagine trying that on a computer slower than my old laptop running Windows 8, unless your drivers are highly optimized. I wouldn't bother upgrading your APU if I were you because your APU is in a BGA configuration, therefore it's soldered onto your motherboard, plus you could run into compatibility issues where your BIOS won't recognize the new APU, and possible thermal issues.
