They listed the minimum system requirements in the article, and I also mentioned in my post that they got the release date wrong... tut tut.
Well Chris emailed me with this:
Just wanted to let you know that the minimum specs posted alongside
our preview came straight from Rockstar. They also sent along some
recommended specs, in case you're interested. And yea, looks like we
goofed on the release date, I'll work on getting that fixed.
1GHz Intel Pentium III or AMD Athlon Processor
256 MB of RAM
8 speed DVD-ROM Drive
3.6 GB of free Hard Disk space for a minimal install
64 MB Video Card with DirectX 9 compatible drivers ("GeForce3" or better)
DirectX 9 compatible Stereo Sound Card
Intel Pentium 4 or AMD Athlon XP processor (or better)
384(+) MB of RAM
16 speed DVD-ROM drive
4.7 GB of free Hard Disk space for a full install
128(+) MB Video Card with DirectX 9 compatible drivers ("GeForce4" or better)
DirectX 9 compatible Surround Sound Card
Game pad with twin axis analog controls (USB or Joystick Port)

So we're the first fansite to have these specs, and they look a pretty logical increase in technology from Vice City so I'm quite sure these are real. I've put them on the System Requirements page for easier viewing.
If you haven't got the recommended hardware then I recommend you get it in order to heighten your gaming experience!
