I can agree with QuanticRiver fully. I am just getting back into things. I am starting to build my wifes but I think I will upgrade and then push her my old board and hardware as all she needs to do is buy a case at that point. Right now, prices are absolutely insane here in the US. Normally from scratch I will start with a barebones system to build up. Right now basic barebones are like $1200. A lot of manufacturers have also moved to proprietary things that make it difficult to upgrade i.e. dell, alienware, cyberpower pc. Just tiny things. That being said to get HD 1080p you can really truly cheap out on hardware as there isn't a lot of power you need. I am running 7th gen 1151 and it gets that job done easily. Keep the ram speeds high as well with as low of latency as you can find. I have been looking for NVME compatible boards under my 1151 socket and havent found anything that isnt an arm and a leg. Boards that used to cost me $120 are now like $400. A good tool to check prices is PC part picker. it will also tell you of compatibility issues as well. With that being said, there are others that manufacturers also put out, NZXT build, Newegg, etc.. Buy your components anywhere but amazon as well. Amazon is usually an additional 20-100$ more expensive although sometimes you will get good deals. If you are looking for modern it may be a good idea to stick to LGA1200 and up sockets. AMD used to be the best bang for the buck in processors but they also run hot which is partially why I prefer intel. There are other things we can go into but people won't like that conversation so I implore you to research on your own to come to that conclusion. I would track prices once you start getting your list together to start watching when they drop. If you have any specific questions please ask. we can all help point you in a good direction. What I will ask though to start off, what is your budget?
