I am currently trying top buy a new processor for my desktop computer. But I am a little lost on what to get. I am interested in getting the Intel Core 2 duo E8500. Does this come with hyperthreading? Or is Hyperthreading no longer used? Also would it be better to get the Core 2 duo or the Pentium D? I am looking at doing some high end applications and running several programs at once. If anyone can give me some advice I would much appreciate it. Thanks!!
