Power consumption, temperature, and noise levels are very encouraging. :D

I m not much impressed with these cards.
There is no point if upgrade for those who already have a 4870/4890/GTS 250/GTX 260.

Shubham1401 - The 5770 and 5750 were not meant to be an upgrade for any of the cards you mentioned. That was made clear in the technical reviews. The cards were meant for mid-level use much like the 4770 introduced earlier this year. Hardcore gamers who want high end cards will have to wait a little longer.

5770 is a huge disappointment in my eyes. What a waste of money

Why??? This is a MID RANGE card that near enough matched the spec of last generations top dog - what's not to like...

It's direct competetor from Nvidia could be considered the GT250, and it's pissin all over that!

Will a Corsair CX400 handle 5770?
I know they recommend a 450w But CX400 is a very good PSU...

shubham - I have not seen the current (amps) requirement for the 12 volt rail(s) yet so I don't know.
