Looking to move to 1440p gaming from 1080p

I currently use a single 1080p monitor (1ms response) and want to move to 1440. What are some monitors to look at that dont cost a fortune .And Is my system capable at playing at 1440p ?
im using a:
radeon 7870 2gb
8 gigs of ram
an i5 4670k

your gpu is the only reason you will not beable to play at 1440p see if you can get a gpu with 4 or 3 gb ram on it

Get a FW900 or another CRT. Your system might not be capable of 2304x1440, but you can always drop down to 2048x1280 or 1920x1200.
