Someone help me with Graphic Cards? Hey there Basil. So I'm not the type of guy who knows much about computers or tech related stuff in general. However, I would like to upgrade my graphics card to keep up with the latest games (it seems as if though it is my graphics card that cannot handle these games). My current computer is: --> HP --> Model: p6153f I haven't touched it at all ever since I've purchased it (everything is default), so I was wondering if people knew whether or not all graphic cards would fit in the tower. Also, could someone explain to me what a "Low Profile" graphics card is? Lastly, these are the possible graphic cards I'm looking at. If anyone can suggest a better one around this price, please do share w
