Hey guy's I have multiple questions here. I have an older hp5700 using dual e2160 processors at 1.8gh. I am stuck with two standard pci slots and an "ADD2 support only slot". #1- I need to know if I need a low profile graphics card or not, all I can tell you is the tower itself is about five inches wide standing up. #2- What is the best card I can get within a decent price range? I am not to savvy with computers but I can take advice and follow directions pretty well. Any help would be greatly appreciated.
