How important is DDR3 in gaming today?

Hey! I am working on a new build, and I was wondering how important DDR3 is. I was hoping to save a few bucks by reusing some old DDR2 RAM, but I've had a bunch of people telling me to upgrade, but they cannot tell me specifically why. I'm currently using the DDR2 memory and I haven't had any issues playing many games. The games I have a hard time playing are ones that demand a better CPU. So can I sneak by with DDR2 for a couple of years? I don't want to play Crysis 2 or anything. The game I'm most concerned about is a Unreal Engine 3 based sequal to the FPS Red Orchestra. In two years I'll just buy a new mobo and memory if it becomes an issue. I mean when they list system requirments they typically just say 2 gigs 3 gigs, not naming DDR3....so is this important? I haven't made up my mind on a GPU yet, but it'll be enough.

tldr: Can I sneak by with DDR2 RAM and still play most games at mid/high settings with a good graphics card?

Thanks for any replies!

Yep, you should be fine as long as you have enough ddr2.

usually for most people the change to ddr3 will bring benefits because it usually means they are changin to a new socket type witha much better CPU then their old ddr2 core 2 duo or amd

i love you guys....

just what i wanted to hear. as for a cpu i'm getting a AMD x4 3.0 which should handle that UE3 game I was talking about.

on a side note...whats the deal with computers and RAM these days. i look at the sales ads in the newspaper and the computers have like 4...5 gigs. that seems silly to me.

thanks again.

most video editing programs arent 64bit yet anyway. i am currently using and i7 930 with 6gb of ram and even when fully rendering out HD footage....teh damn program wont go anywhere near 5gb ram usage.

Only reason to get a DDR3 board is for future proofing, really.
