The  Hp monitor is not 19 inches its 15 the mouse came broken and the keyboard sticks you have to type twice on some letters. The tower is in fact 3.10 GHZ it does have 8 gb ram and yes it does work did i mention you can adjust the monitor to your liking which is great for those who cant sit very long . so over all i give this product a 3 out of 5 .
