Er, that's kinda silly.
It's true an iMac refresh is due. It's unlikely to be anything major though, probably a bump in video and suchlike tinkering around the edges.
The i7 iMac is "old" in that sense alone.
Re "poor", no way. I mean, presuming you know what the deal is with Mac hardware (ie. they are never going to compete head to head with PC gamer rigs or anything, that's not what they are for), totally no. They are amazingly cool. 😀
