NoIdeaWutImDoing.

Hi. I'm just looking for a card that's no more than $200, that can get me over 80fps in Rocket League, CSGO, and more less Fortnite. I'm using a 1600x900 monitor, MicroATX ASUS Motherboard, AMD A8 7600 CPU, and an MSI Radeon R7 240 GPU *smh*. My main problem is that I am kind of torn on which GPU to buy. I'm mainly looking for the GeForce GTX 1050 ti, but I don't know what the ti stands for, and which brand to buy from. I see MSI, Nvidia, EVGA, etc. I just don't know if one is better than the other. After all, they have the same name, so why would they be different performance wise? Please help. Thanks, Andrew PS. Dumb your responses down a little bit. I don't know all the terms and stuff, but I'm not computer illiterate.
