Bad thing about using TV's as your computer monitor, is latency.
Some tv's have significant delay processing the video signal input from your computer, to the display screen. For a tv normally this is inconsequential...
but if you're gaming on it, it has its consequences, showing up as input lag.
You click the button to fire your blaster...
... and 200ms later your blaster fires. (extreme example)
Make sure if you get a tv that it has a 'gaming mode' or somesuch.
IPS monitors that size also get expensive, fast.

For me, the fast answer would be to go with the monitor. I _might_ find a tv I would like if I searched extensively before making the purchase. (and believe me, I've considered that option. I have my computer on a corner desk unit... I easily have room to put a 40-50 inch unit on the desk instead of the monitor I'm currently using, which is an HP2475w (24inch IPS monitor... very nice one too)
