Why would you run a 3700 at Stock?
Why would you buy ANY chip this month knowing next month they all get pricecuts? In 5 weeks an X2 3800 will cost about $160 (I've heard both $155 and $170). Heck, you'll get a dual-core Athlon 64 chip that overclocks to beat the crap-arse netburst garbage for about $40 more, and you wont' have to worry about clock throttling. And it will be better in games.
Put the brakes on your build.
