MBReview has finished a review of Intel's budget-oriented Pentium D processor, the 820.

All in all, Intel has an excellent offering in the Pentium D from a price vantage point alone. The processor does run quite a bit cooler than the Extreme Edition 840, given that it's clocked down at 2.80GHz versus the 3.20GHz of the Extreme Edition 840. The Pentium D 820 doesn't feature the clock control features for cooling of the Extreme Edition either, because the lowest multiplier is 14x, the default multiplier of the 820.
