Just to clarify, Some people are saying that Athlon 4 SSE+ is slower than SSE2. SSE+ was wasn't made to compete with SSE2. AMD's Hammer will have Full SSE2, at which time there will be software made for it. SSE+ I believe is just added to even up the optimized software that was running better on Pentiums. Now the playing Field is fair. So don't get it twisted. What i'm really interested in seeing is what benefits the enchancements to the core will have to Motherboards with DDR. From what i've read already the new enchancements will take advantage of greater FSB speed and Memory bandwidth.
