I actually meant 4890, I was pretty tired when I typed that, but ty for correcting I was thinking the 5770 would be faster than the 4890 by a bit, I'm just curious to see how the missing SP's will impact it and if it will be above the 4890 or between the 4870 and 4890.

Lol, next the cards will end up supplying the system w/ power instead of taking from it!

The idle and max board powers are rated by AMD at 18W and 108W
Very nice indeed, actually lower than a 4850 with more memory bandwidth. 2 of these in crossfire would probably eat less power than my single 4890.

Those power consumption numbers are awesome! Anyone knows how much the 5850 and 5870 downclock when not in games?
Maybe by using Rivatuner/ATT we'll be able to shave off a few more watts from the idle consumption...

i thought about it..probably at high resolution the 5770's bw limits too much, but with normal resolutions (1680*1050 or less) this shouldn't happen,or i'mwrong?

Remember, 4550 only has 80SP... The low-end will definitely be a good HTPC buy once it comes around, what with all the new connectivity options and undoubtably improved performance.

retail prices seem a little high, but that is probably to make sure they can clear out remaining 4770, 4850, 4870 stock before the 5750/5770 go into discount mode. Looks like great replacement models, but I will be happy with my 4890 for quite some time.
