So basically, I wanted to find a way to play games without lagging everywhere and the only thing that is bad on my laptop is the graphics card, so somehow I stumbled into this eGPU page and hopefully someone can help me basically understand how all of this works or at least attempt to help me out. So I have an Dell Inspiron 17 7000 series and ill basically copy and paste the processor if that is relevant information. The processor is a Intel(R) core(TM) i5-5200U CPU @ 2.20GHz so I have no idea what most of this means because when it comes to laptops and modification I am just completely clueless. I was just hoping to get an answer from someone if I could even have a eGPU setup and what it would cost me for that and if it is even worth doing. I know this is where people who know everything about this stuff, but I am just really interested to see if I could actually just upgrade graphics cards without buying a brand new computer, and hopefully somebody can help a clueless man. Thank you for reading and replying if you choose to.
