ok, I can admit that I have a lot of reading to do. I have worked with computers with over 20 years experiance. The main difference between 8 and 16 bit was the size of the variables the maths can handle. As you get better this decreases because the numbers inside the varialbles make less difference. In other words the software benifits less as the hardware gets better to a point. "john dont jump at me for this one hear me out". The hardware now is 64 bit. This means the OS can handle a stupid amount of ram, which the mother boards have not caught up with. If they had there would be about 20 ram slots. Try that for prefetch. If the hardware and software worked together we would have a realy good system. It can not do this. I say give it a year or two to let the hardware catch up.
