Many people have had the same queries as yourself. Do a search of the TFP before posting a question that has already been answered before. Members come and go, each leaving some part of themselves on the forum. Do a search before you ask about routers, video cards, power supplies. As tech equipment progresses, so does the board. But, please, stop asking about how the wheel works! Do a search before you ask! Any new info goes into a link you might offer, please offer new stuff. Stop asking for the same old stuff that exists in this great wealth of knowledge database you can search for free.
The rant is over. Thanks for your time.
