I was expecting quite descent things from this card, its more powerful than my previous card which could run MW2 on max with no problems at all but this 5770 struggles and runs pretty slow, a few other games ive noticed this on aswell. Its annoying and very tempting to just put the old card back in
 
This is worrying me as i've bought my sons a 5770 each for christmas to replace their 8800GT's They mostly play CSS and MW2 @ 1680x1050. I can't find a definative answer to how much improvement the 5770 is over a 8800GT and all i'm seeing lately is posts of dissapointment.

They'll enjoy them.

I've been running one for a week and it played COD 4 MW and Dirt 2 fine at 1920x1200 :)

Back onto Crossfire now though due to new Mobo.
 
Did you remove all the Nvidia drivers? then sweep up with Driver Cleaner? :)

Benched them with 3dmark Vantage? (the score might reveal if you have a problem!)
 
I would say always do a fresh install of windows tbh. When I put my 5770 in (previous 4850), then uninstalled/reinstalled new driver, all of the games were pretty juddery and worse than the 4850. I then wiped the PC and put a fresh windows on and everything was suddenly silky smooth @1920x1080 2xFSAA max settings (MW2,GRID,Resident Evil 5). I would hazard a guess that windows compiles itself around your hardware as it installs a bit like linux. Then when you replace something it doesn't quite run up to scratch. I could even play MW2 maxed out with 4xFSAA and it was still smooth as butter 90% of the time, GRID runs silky smooth maxed out with 8xFSAA :)
 
dont even bother doing a fresh install of windows just to change graphics cards

down load either driver cleaner or driver sweeper (google) , install and create a short cut to your desktop,Uninstall old drivers and physically remove old card and install new card, reboot into safe mode (F8 button while pc boots) , load safe mode and find the shortcut on your desktop, run cleaner and search for your old drivers to clean, once cleaned reboot and install new drivers , dont forgot to download and install .net framework packs if installing ATI drivers,these usually need to be installed BEFORE the ATI drivers


job done
 
don't use driver cleaner or driver sweeper because it could delete something it shouldn't... i tryed this once and it messed up windows..

just uninstall using windows uninstaller then go in to device manager and delete the graphic card driver, then reboot and install the least ati drivers
