Buying new (used) gaming pc

[El Greco]

Hi Guys!

First of all I wish everyone reading this happy Christmas and holidays in general.

After two years of just using my ThinkPad as mine and the whole family's main driver, I think that it's time for an upgrade.

The PC should be future proof for at least the next 5 years. The only things I'd change would be the ssd (if there's need for more), the ram (same here) and the gpu (it's used for AAA titles in 1440p). 

My only worry is the mainboard. I personally would prefer a Asus X99 Deluxe/Rampage V or an MSI XPower Gaming Titanium.

The reasons are the wider connectivity and the better and more attractive build quality.

And excuse me for any possible orthography or grammar mistakes. (I am from Germany)
