Hello,i need a video card driver for HD 4850 for Windows 7 but on AMD website there is no driver for this card. There is only for HD 4830,HD 4850X2,HD 4860......but none for HD 4850. I tried to install the one for HD 4850X2 and it worked but 3D performance in games is really bad and before you say anything,yes,i know this is an old card but this is a PC from a person on which system i just did a fresh windows install and now he can not play games like he was able to before windows reinstall because there is something wrong with driver. Do you have some suggestion? Should i try the one for HD 4830 or HD 4860? I used to have HD 4830 couple years ago and it was running games better than this HD 4850 right now and it shouldn't be.
