look more than twice a day, I'd email scan and ask when they post the new deliveries on the site, what time in the day. They should know if you get the right tech support.
and yes these cards run a little warm. But not much warmer than a GTX 280, or the 285. the 295 is hotter, and the 5970 is about the same. ALLL the reviews you guys saw saying these things reach 96c.. was all crap. Yea with the fan set to AUTO, running furmark extreme heat benchmark (the only program that will get that much heat out) can get over 90c. but just manually set the fan to something like 75% and they wont go over 80c.. witch makes them Just as cool temperature wise as anything from ati.. The reviewers were a little harsh.
I use eVGA precision and just set fan speed manually. Right now in SLI my 480's are idling at 41c and 45c and yesterday while benchmarking my highest temp was 81c highly overclocked and with a little extra voltage. so heat's really not an issue
and yes the 480 is just shy of double the performance of the 285. I'd sell that and get a 480. Its a large increase in performance, but it's also DX11, and it plays physx games better than any card with a dedicated physx card. it really is pretty solid. This 480
