Well at the same clock the 7xxx and 6xxx are apparently the same speed in almost all cases. 7xxx is a bit more power efficient though, and can hence overclock a bit more. But yes, not a big leap this time at all. There is a new chipset generation to go with it, although apparently some of the existing 100 series boards can already support the new chip at least with a bios update. > There are useful features added to the processors since the Haswell > generation.

Well at least on some models they are improving graphics, but I am not sure that is the case on all models. I still have a happy Core2 Q6600 running, which was released 10 years ago, and I would not consider it a slow machine. Sure it doesn't match my i7-3960X machine, but that would not be a fair comparison anyhow. -- Len Sorensen --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk
