smp: I alway buy OEM CPU's rather than retail ones. Like Mem said, that gives you the flexibility to buy the heatsink/fan combo of your choice. And it's inevitable that that will be better than the stock combo that comes with a retail CPU. And the 1-year (OEM) vs. 3-year (retail) warranty is a moot point as far as I'm concerned. It's rare that I have the same CPU in my system for 12 months, let alone 3 years.
