24" Monitor for gaming?

[Swordfish125]

One of my current monitors has decided to die on me, so I'm looking at a new one

Currently I'm running 1680x1050, so I want to go higher, So I think a 24" will be more than big enough. Monitor tech seems to have moved on a lot, since I lost bought, so I'm lost.

I have a budget of around £150 (could go a little higher). I will have a Samsung T200HD as a second monitor.

I've seen these:

I do like samsung, I have a Samsung TV (and my second monitor), but not really too fussed.

The only use is gaming really, running a GTX480 atm. Would prefer DVI connnections to HDMI as I have cables.
No speakers needed, dont really like speakers on monitors tbh.

Hope you can help, or suggest some I've missed!

Thanks
