mobo/cpu upgrade

[Big10Fan]

Looking for a mobo/cpu upgrade to pair with an ati 4890 for gaming. No immediate intentions to overclock, just run on stock cooler. I missed out on that asus m4a78/720BE for $180 a couple weeks ago, and these are the best I have found since then. MoBo needs integrated graphics because I like to have it as a backup and under $200.

this first one is only $140, but uses DDR2, any con to DDR2 with a AM3 CPU?

$170 for a regular ATX AM3 board to support DDR3

I'm skeptical about Biostar, but this combo exists with the 550 for $173

Wait a couple weeks for more combos with the 550BE?

There is virtually no noticeable performance difference between DDR2 and DDR3 RAM with the current Phenom II line-up.

Any of the three combos would work, but I don't know whether or not additional/better combo deals would be available any time soon.
