Video Cards versions and pricing, cooling and performance.

I am sure you many of you see video cards that come out with dual fans, aditional cooling pipes, higher clock speeds then the stock card. However all of these features cost money for instance if we take the a 560 GTX from Asus which has dual fans, nice metal frame, and aditional support for the card so it won't bend inside the case. All of these features cost money while they may make the lifespan of your card longer or perform a bit faster doing certain tasks is usually not worth your money.

When buying hardware for your computer you have to know what your are going to do with the system for instance if you are never going to overclock your CPU then there is no point in buying a K series cpu. Also on many forums you may hear "oh just get the latest one, the one with dual fans". You have to make a choice which versions of parts you want since if you are on a budget buying a part that may not have dual fans, or a K beside it may end up saving you over 100$.
