That would be my choice as well, or get i5 on that other socket. i7 on i5 socket just seems like a way to make a cheaper i7 to me, ie. nerf it.
I'd give it a little more time though, let others chime in. Especially someone who actually used the equipment; still on DDR2 and Core2 myself. Always better to have multiple opinions, even if they contradict.
