@im2thecrowe: That's completely true that a C2D build would outperform it. But...
...a lot of AM2 boards can handle AM3's as drop-in replacements. This is often your most cost effective option. Check the motherboard manufacturer website and see if your board has AM3 compatibility. You'll still have to adhere to max CPU wattage (95W or 125W typically), but it's the cheapest upgrade path if it's compatible.
Even if compatibility isn't listed (such is the case with Abit mobos), it doesn't mean it's not compatible. If possible, find a friend who will let you test their AM3 after you do some research.
