I need real world answers. I have read all the WIKI deffinitions and comparisons, no help. what are the differences Between the 2. I am not an engineer so please talk down to me so I understand what you may have to offer. Most sites and Blogs are bios'ed one way or another and i not looking for what is better unless it overwhelming to one or another Just differences if there are any. have heard that HT may be faster but with bottle neck problems and lower latencies with nearly idneticle band widths which make the QPI more effective?
