27 and I don't care about specs anymore, to a certain point.
I'm running a 3 year old desktop (E6600, 2GB, 8800 GTS) which was great for gaming (and probably still is for some titles). I stopped gaming about a year ago though as other things have occupied my time.
Now I just use it to manage mp3s, torrent videos, email and surf the web. It's more than snappy enough for that. My old P4 at work, while it handled work programs and surfing, was pretty slow for multitasking - if that was my home machine, I would have gotten rid of it.
I'll probably keep this machine another 2-3 years or until it's too underpowered for basic stuff, and then move to a mainstream laptop at that point.
