I decided to go ninja style and get a silent GPU for my PC but don't know a lot about GPU's as I don't play games on my PC so usually just buy something cheap and cheerful. The reason I don't just use onboard graphics is because I sometimes use two monitors.

Is there a significant difference between these besides price and brand? They seem pretty much alike to my untrained eye.

Here are the candidates:

Thanks in advance for any help. Other suggestions are welcome if these all suck too badly but keep them inexpensive (under 125.00 US) please. Also I want to stick to NVIDIA so I can use CUDA video encoding technology.
