Are you sure you want to go with IPS panels? For gaming and movies, it's not the best option, a TN panel is.
Something like a ASUS VH238H or a ASUS VS248H-P is a good choice.
If you still want IPS, the U2312HM is good. Another option is the ASUS VN248H-P, which is a bit cheaper(you won't get the pivot & height adjustments).
