A 30" monitor would be great for photo editing (huge resolution increase), but could be tough for gaming in terms of native resolution (requiring top-end hardware) and refresh rate.
If your budget is almost £1000 and you're serious about colour accuracy and image quality, I'd suggest you look at the Eizo range - they are the cream.
