It's my friends computer,  he's selling it. No solid price yet,  I'll try finding out. None of this means anything to me, I was hoping you computer people could tell me if I should even consider buying this thing just based on those specs.

Depends on what kind of games you play. Gtx 560ti is pretty old
but will run games quite well tbh (~20 fps on Far Cry 3 on 1080p on ultra settings for example
which gives you some guiding light on how it will perform on other games.)
Core i5 is great for gaming and 16 GB of RAM is more than enough.

It's a rather 'old' gaming setup but it depends on what kind of games you play to make it a worth it purchase.

Depends on how old it is too. New this would cost around 600eu i think (just the case, monitor etc excluded). It's a good solid pc and will be able to run a lot of things at the same time, gpu doesn't matter that much that it's old, the cpu and ram will be sufficient to run most aaa games quite fluent.
