Anything based on the "Ultra Durable 2" series looks good for the 1st 3, nothing is "future proof" however. Rumor has it that Nehalem may be a new socket entirely anyhow, so that wouldn't be future proof.
"Now if the 4870x2 was actually notably faster than the 280 for about the same price, then I might even take a chance on it. However, that won't be the case."
I would wait about a week.
The x38 Mobos should be coming out anytime.
The official release date is the 23rd of this month, but rumor has it many vendors are going to release early.
If you are in a "Price makes no difference, you probably want one of those."

I am in a similar position. Apparently many people in this forum and Hardforum prefer the Abit IP35-Pro. I am deciding if I shluld wait for the X38 or take the IP35-Pro now !
My concerns on the X38 are it is a new chipset and it will be expensive. Also, there will be growing pain as BIOS usually takes time to mature !
