You do realize that text will look terrible on a TV being used as a monitor, right? Especially on a very large unit, even on a 1080p model? And also that televisions don't tend to HAVE low response times like many monitors do.
So long as you realize that a TV with similar specs isn't a monitor, in any regard, then ok.
You could do something like this. Insignia is Best buy's house brand and are typically pretty good in terms of quality compared to cheap off brand chinese made units. Probably one of the best 1080p televisions of this size you are likely to find for under 200 bucks.
