Well I poked around, there is an open box Asus M4A79 Deluxe for $133 and the 940 is $215. If I went with that and used my current G.Skill PI black DDR2-800, I could save about $150 over going AM3.
So the question is I suppose, is AM3 worth the extra $150? Of course the savings is from that board being open box - if it was new I'd be saving a little over $80 if I was to go with that board. To be honest most of the AM2+ boards don't appeal much to me much for some reason. Too many with SB600, or hideous colors (yeah yeah I know), just seems there is more "stuff" available on the AM3 boards for the same or lesser price, like the M4A79 Deluxe is $200 new but the MSI 790FX-GD70 gives more for $20 less.
Decisions, decisions....
