If I had to choose I would opt for the Dell Ultrasharp U2312HM, but only as I do some photo editing as well (yes, it would still be on a budget). While it has an IPS panel, it is still regarded as pretty fast, here is a review: http://www.tftcentral.co.uk/reviews/dell_u2312hm.htm. It includes comparisons to other screens, even 120hz monitors.
