Intel Core 2 Duo E6400 - Core 2 Duo Conroe Dual-Core 2.13 GHz LGA 775 65W Processor - BX80557E6400

Pros: At stock speeds, blows away AMD's FX-62. The Core 2 Duo processors are actually (proven) to be more overclockable than the Netburst CPU's. Paired up with a P5W DH Deluxe, I have my E6400 running stable at 3.68ghz (460x8) with the pencil vmch mod done to the motherboard. Without the mod you shouldn't run into trouble until around the 400mhz fsb mark (giving you 3.2ghz.) I suggest you atleast get a good air cooling solution if you are going to be overclocking. Currently, with such a high overclock, my cpu runs (on the nautilus 500 WC kit) 31*c idle and 35*c under full load.

If anyone is wondering, newegg is shipping the E6400 B2's which are more overclockable than the B1's that most etailers are selling.

Cons: NONE! DON'T BE FOOLED ABOUT THE 2M L2 CACHE! THERE IS ONLY BETWEEN .03-3% IN PERFORMANCE VS. 4M L2 CACHE!

Overall Review: Save the money and get a good value ram 2GB kit unless you are going for world records. The increase in FSB has more impact on your memory performance than the speed of your ram itself. Check out anandtech's conroe review for suggested value ram kits. Make sure you get one of the best motherboards, currently the most overclockable boards are:
975X: Asus P5W DH Deluxe, Intel Bad Axe
965: Asus P5B Deluxe

You'll get better results with one of these motherboards paired up with this cpu vs. E6600 with a mediocre board.

Hope this helps!

Pros: It showed up on time

Cons: DOA

Overall Review: Will review again when a working processor shows up
