I just picked one up at the local Microcenter on the 13th. Sales guy said the price had gone up to $199.99, but it rang up for $189.99. I'm sure by now it's up to $200.
I went back yesterday and they still had easily at least 10 left on the shelves. Strangely enough, they were all out of the $70 E2160s and almost out of the $59 Dual-Core Celeron E1200 (1 left). I too have thought about buying them out and selling on eBay, but meh.
I went cheap on the MoBo for now--it's an ASUS P5GC-MX/1333 that I picked up for <$50. I couldn't get it to post and was all pissed, then I tried it with a Pentium D 805 I had and it booted. Turns out I had to upgrade the BIOS to get it ready for Wolfdale. Even though the box says "ready for 45nm" right on it.
Anyway got it up to around 3.22 GHz on that MoBo with 1GB of extra DDR2 667 (that reads at 533 for some reason). That's 9x356 or so. Pretty sure that's memory limited, plus I am not too familiar with the options on that board.
The HSF is TINY. Just like the pic. Loaded to the gills with Folding@Home, it's running at 26 degrees. I'm amazed. I have trouble keeping the aforementioned Pentium D under 70 degrees OCed to 3.42. Albeit with not the greatest heat sink, but it's monstrous compared to the one that came with the e8400.
Can't wait to really test this thing out with better memory and/or mobo. I'll be happy with 4GHz.
