correct, you can essentially cut atom's 6990 speeds in half. it will be a little bit faster due to higher clocks, but that will give you a good estimate.
I believe d3ad0ne may also have some 6970 benchmarks posted at http://ob-security.info/ as he was using 6970s before he upgraded to 7970s.
6970 is currently the 4th best card you can buy at the moment; general order of preference being 6990, 7970, 5970, 6970, 5870 (although #1 and #2 are open for debate, i personally prefer 7970 over 6990.) so if you can get 6970s for a good price, go for it.
