Thanks for the input thus far, please keep it coming. A follow-up Q. on processors. I've understood that cache is important and faster clock speed is preferable over multiple cores. Given that, with these choices, would you go with the low end i7 dual core or spend the money for more cache?
I don't think the top two make much sense, money wise, so the choice is the 620 vs. the 720. The 620 will boost (overclock) to 3.33 GHz and the 720 will boost to 2.80 GHz, but the 720 has 50% more cache. Which is more important? Doug Schaefer
