The AthlonII X2 240 would be closest. It's slightly cheaper than the E5300 and slightly higher clock and has integrated memory controller and hypertransport so should perform a bit better.

They both overclock great (athlon X2 and E5200), however the E5200 platform is s775 which is obsolete, meaning no more cpu's will be made. So unless your current mobo supports the E5200, then your better off going with the AMD platform.
AMD still plans to make more cpu's for the AM2+/AM3 platform, including new X3's X4's and X6's (I'm pretty sure AMD plans to make the X6's backwards compatible with DDR2 as well)
Soooooo.....even if the AMD platform was more expensive and it's not, at least it has upgradeability.

Is there a AM4 socket for AMD? If not, then whats the "cheapest" of the best for a AM3 socket motherboard? DDR2/3 dosn't matter for me. Slapping in 8GB's of DDR2 is good enough.
I dont think you understand. A AM3 motherboard only takes DDR3. A AM2+ motherboard only takes DDR2.
So if your planning on using DDR2 you cant use AM3 mobo.
For $99 you can get a X4 620 and overclock it to 3ghz+. Otherwise theres a bunch of new X3's that are pretty fast and very overclockable for about the same price or a little less.
