Yeah, that's the problem with that description. I could give mine as:
2 2.66GHz 2 Core CPUs
10 GB RAM
NVIDIA GeForce 8800 GT
And at quick look it would seem like I'm not far behind the OP. But that's a 2008 Mac Pro, and that storage is distributed across three internal disks, only one of which is an SSD. (I'm not counting the external.) I'm stuck with 10.7 as my os. I'd love to upgrade, but I don't have the money.
(Note that the box is fairly heavily upgraded from when new - I've added about 6GB of RAM, and replaced all the disks since I've bought it. This is also the third graphics card I've had in it. But all those updates were done a while ago, when I had a job. On the other hand, it's still faster than my parent's much newer MacBooks and iMac, because I've upgraded intelligently. If it wasn't for the 32-Bit BIOS it would still be a decent computer for 95% of current software.)
