Summary: I got this to upgrade an older machine to process data at Einstein@home. It isn't the most modern or fastest cpu around but it works. For the money it is a pretty good upgrade since it works with the old motherboard and memory. I don't mind being a couple generations behind as long as it works well.
Summary: This processor is good, when I got it I and install it, I was not able to install the fan cooler that come with the processor in the box. I have to use my old one that was with the old Processor on my pc.
Summary: I bought this back in December for about $200 used. Even though the price was a little high I thought it was worth it since I plan on using my Dell Dimension E520 (upgraded from a Pentium D 820) for a few more years than planned.
Pros: good bang for buck and powerful... Cons: gets very hot

Summary: Q6700 was put into my HP DC7800, replacing the current E6550. The Q6700 clocks at 2.660GHz, and the E6550 clocks at 2.331GHz, even with just the 300MHz increase the performance has increased dramatically, most noticeable in gaming and movie making applications.
Summary: I did a recent upgrade on my home PC from a P3.2 HT to one of these. There is just no comparrison in terms of raw processing speed. 4 actual processing cores, each running at 2.66 Ghz lots of level 2 cache on the chip and a front side bus of 1066 MHz.
