ROFL!!!!! Oh criminey. I was wanting to write a quick update to this, but I just noticed that it's been exactly a year since the last post. Wow.
So... the gaming aspect of this thing (Or the absolute chugginess thereof) got to me, about midway through 2012. So I finally I decided 5 years was a good amount of time for my old PC, and that it was time to upgrade.
This year, I bought a new PC, one with an
Intel Core i7 3930K CPU and an
EVGA Geforce 670 Superclocked w/ 4GB RAM. I did a lot of research on the matter, and it was pretty unanimous online that if the gaming resolution is 27" or above, you'll potentially experience memory bottlenecks with 2GB. And in all of the benchmarks online, the difference between a 670 and a 680 is like $250 in price, and only 5 frames or so in performance.
So with that done and dusted, this monitor truly shines now. Every single game I've thrown at it (Including crazy high-spec ones like
Saints Row The Third) runs great! Thanks to the 4GB of RAM, MOST can handle max AA as well, but sometimes they choke (But that's okay. At 30" you won't notice.

).
One other thing I discovered recently (Which is really cool) is the monitor sets itself up as a USB speaker (ie, when you go into the Sound control panel, the monitor is a valid option) which lets the PC stream its audio output to the monitor along the same USB line as the peripherals (ie keyboard etc). This audio is then routed out of the monitor via 3.5mm jacks that can do up to 5.1 surround sound. Incidentally, I have my Xbox 360 also plugged into the monitor via HDMI.
What I'm actually getting at here is that the monitor is able to dynamically route audio out of either my PC or Xbox to my speakers completely dynamically without touching the audio cables. Up until now, I didn't know audio was routed through the USB, so whenever I was planning on playing my Xbox, I was manually unplugging the audio cables.

So. To sum it all up. This monitor is awesome. Really awesome. I've had it for a year now and I still love it as much as when I bought it.

While I'd still recommend you to get one... I've just heard that its successor, (presumably the Dell U3013) is slated for release in a couple months time. So, might as well wait for that one now.
