Using a 50" TV for general computing

Just to get this out of the way, this is 100% serious, not a troll thread. I have been looking at TVs for a while and am considering getting one in the range of 50" by October possibly if budget permits. I like my 26" screen but it is starting to feel small to me as a hardcore gaming match a couple days ago showed me.

I have heard of people that have done this in the past but I have heard mixed things about it, such as HDMI having bad quality and brightness being lacking, ghosting, etc. Are the individual pixels noticeable on a screen that size at 4-8 feet or do they blend pretty well? Also, is the 3D on them any good? I have heard that for games that support it such as Mirrors Edge, that it is pretty trippy playing on it.

Here is one of several screens I am looking at right now:

No.

you want a minimum of a 5ms response time and tv has nothing close to that (around 9 or 10 ms usually (?) )   and the awful pixel density will be very noticeable within 5 feet. (look at your standard monitor pixels and your tv's pixels there is a significant size difference) if you plan on sitting across the room from your monitor go ahead and buy a tv, BUT if you are going to be up close and personal with your monitor just get a wide monitor (http://www.newegg.com/Product/Product.aspx?Item=N82E16824005396) or another one of what you already have and run it in a dual display setup. 

I keep my pc hooked up to a 46" tv and just use a wireless keyboard/mouse and sit on my couch...I assume the quality of a desktop monitor would be much better but so far I don't have any problems using my TV. Gaming has the same responsiveness as an xbox 360 in my opinion. 

Holy mother of dog turds, that is wide. I didn't even know those existed. :P But with the weird resolution and aspect ratio, wouldn't most games older than a couple years have issues displaying it? That would be a little more feasible than a TV, since my living room is set up very weird.

Im doing the same thing as tanner, gamings good on it but im used to garbadge so i dont know how it would compare to a true gaming monitor

Well, even though I have a 1080p monitor, it has a TN panel which is kind of shitty. Colors are not exactly great and the viewing angle is pretty crappy, but it was a good deal when I got it several years ago. I probably wouldn't ever be able to get the configuration set up for a TV, but it would be pretty fucking ace to play FC3 on a TV with surround sound.
