Why do I have to buy everything? Things like my actual audio card or ethernet card wouldn't be good for a new motherboard? Well I'm 15 so I still depend on my parents. I think that I could buy new stuff for my PC the next year and my budget is about €200 I think. But at this point I think it's more convenient to buy a new PC, isn't it?
I needed it to provide the best online stores in you nation. Also dont forget to compare the prices with a local market. You can buy amazon, you can also try a online retailer that is only in your nation and you know of.
What you generally do with your computer What you need it for?
