True, this pc worked well for long, but.. I would have gladly changed it about 2 years ago.
Now I'm going to resist until Win9, hoping that it won't be s**t.
(also, Intel's Skylake and the Geforce 980 seem quite yummy, even if probably too expensive for like 1+ more years)

Oh, and did I remember to mention the state-of-the-art 24-key cuneiform keyboard?

Hm. It has a keyboard. And a monitor. And one of those new-fangled mouse thingies too.
