That bundle is actually relatively close to my system, except I have 16 GB of RAM and a 270x. I'm going to agree with legend and say it should be able to run things on medium to medium high without a lot of trouble.
You don't have to worry about thermal compound if you're going to use the stock cooler, since it's included or pre-applied, I can't remember 100%, but go ahead and get some if you're going with an aftermarket cooler for the CPU.
I hate to ask but also is there anything else I should get that u would suggest to make it a better rig and what os should i use or I I should use Linux os that it comes with and if I would need additional fans. Thanks for all the help I really do appreciate it I'm just kinda nervous it's my first build.
