Performance wise,5850>5830>5770 but i agree with posters above,for 1680x1050 a 5770 suffices
i am confused for a 1920x1080 monitor which graphic card to go for ??
5770 was my main choice i am thinking of 5850 nw ... pls advice
5850 -> 1920x1080
wont a 5770 do well ?? or if nt tht thn 5830 coz budget is to be contained
For 1920x1080 i would choose 5850 as well
The HD5770 will be pretty good for 1920x1080. You wont be able to max out the settings on the more intensive games but it will still be a very capable card. If you can't afford the HD5850 then perhaps an HD5770 for now and another in crossfire when you can afford it(if your motherboard is crossfire.) I would forget about the HD5830. It's rather overpriced for it's performance IMO.
