The price on these boards has bounced around a lot.

But for those of you wanting to build a system extremely cheap but still have some flexibility, I don't think you're ever going to be able to dip below $60, much less $35-40

I know personally that the K7S5A will support a 2600+, I have heard some people claim that it will support a 2800+
