I'm in a fix... Do I need DDR3?

[denzlite]

I've got a Pavillion m8100n that I'd like to upgrade so I went out and got:

AMD Phenom II X4 940
G.SKILL 4GB DDR2 1066
ASRock A780GMH/128M AM2+/AM3 AMD 780G

I'd like to repurpose the box/hadrdrive/dvd burner - like to get a micro atx mobo. So these things are shipping right now, but now I got on this Tom's Hardware site and now I'm wondering if I should go with a straight AM3/DDR3 board?!

I'm looking at newEgg and they have AMD II X4 955 Bundle with CORSAIR XMS3 DHX 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 for only about 50 bucks more than the 940/G.Skill.

Only thing is the only micro ATX motherboard that's AM3 is this DFI LP JR 790GX-M3H5 AM3 AMD 790GX that has only one review.

I'm sort of newb so it seems like I should stick with stuff that has a lot written about it.

But I also don't want to buy a new mobo in a year to upgrade cpu/memory...

Any help much appreciated. I guess I should add that my primary use is graphics / video editing / photoshop. I need a fast quad to edit avchd footage.

What are you planning on using this computer for?

 

[denzlite]

Video Editing - DVD/Mpeg2 Encoding - AVCHD editing - Photoshop

Right now I've got a AMD 6400+ / 3 Gig RAM but want to upgrade since sometimes I have a bunch of Adobe CS4 applications open at once. The box is almost always encoding something or other....

the 940 is am2+ so no, and am3 is a waste of money anyway, the most powerful cpu you're going to get on that platform is a 3.6ghz quad core and the next generation of cpu's will beat it.
