Should I continue to wait?

i've given one of my 5770's to my older sister. I couldn't have picked the worse possible timing. later that week 5850's pole-vaulted it's way beyond $310-320. 5870's also continued to rise. my wallet's beginning to pucker out of fear of another price hike- now that some preliminary performance figures for gtx 470/480 are up. I'm thinking of waiting until thuban is released to begin another build in hopes of some cooled off pricing... but until then I'm still in need of a gpu and don't want to be stuck with a 5830, unless the price cools off to a fair sub-$200. I digress, my dog is laying on the keyboard and licking the keys lol. So back to reality, if there are any insiders here in these forums, please help me out in making a good decision!
