Hey guys, I'm back with a mostly function HD4850. I haven't used it in ages, but when I did, It was pretty good except when strained, at which point it would stop working and a restart would be required. Sounds like it could be a cooling issue, but I haven't made any effort to repair it, since I upgraded soon after. Regardless, it's a nice little PCI-E card if you guys ever need to test for defects. I'm going to attempt to get $50 for it. PM me if you're interested or if you know how to fix the problem. If you know a method, I'll do it and let you guys know if it's successful. Thanks!
