Cheap solution for 3 monitors

[cctaylor311]

Currently I have dual monitors on my desk running just fine, and my big screen tv hooked up as well... but am unable to view all three at once. So what I currently do to watch movies and such is just mirror my main monitor and my TV while essentially "disconnecting" the secondary monitor. However, I want to keep this same setup (2 monitors, 1 tv) but add a third desktop monitor. I would like three independent monitors running at once, with the ability to "disconnect" one of them and utilize the tv as a monitor for movies etc... here is the problem. I have a gpu that only supports two outputs at once (hence why i disconnect one monitor to watch stuff on the tv) what is the cheapest way to go about this?
So to recap
Currently: have 2 independent monitors w/ability to switch over to TV
Want: 3 independent monitors w/ability to switch over to TV

My motherboard is the Asus M4A87TD/USB3 it has a single PCI Express 2.0 x 16 and three PCI slots
GPU GTX 460

Can I just buy a cheap video card and add it to a PCI slot? If I do this will it allow me to run 3 monitors independent of each other?

Also, I am not opposed to buying a new GPU in the $200 or less range that will support 3 monitors...just want them all on at the same time obviously and have the ability to switch over to the TV when needed (so technically 4 monitors need to be connected I guess, but only 3 at once is what I would like).

Yep

I am currently using a £25 Asus 5450 running 3 monitors at 1440p.

I have the displayport version, which is very hard to find:

I orignally had a 5450 with HDMI and a 6450 together, but it was very difficult to set up eyefinity with extended desktops to the left / right monitor from the centre one. It works flawlessly, unless you want to play games off course.

Sapphire FLEX cards give you more options for connectivity. They make cheap multi monitor cards (6450), although usually more expensive than the OEM models.
