A few months ago I found myself in a situation with a pair of HD4850s and 3dMark06. I was working on breaking 24,000 marks with 2 HD4850s and a Q9550 CPU. Seemed possible to me. Only problem was that one of my HD4850s died. Around the same time the HD4770 was barely hitting market. I decided to buy one to see how the 40nm gpu power of the HD4770 compared to the HD4850. Turned out the HD4770 worked much better in my system than the HD4850 so I sold the other working HD4850 and bought another HD4770. Since then I have come to appreciate the performance of the HD4770. From time to time I have shared my experiences with the HD4770 and I have discovered that there are people who debate that the HD4850 is better than the HD4770. This thread is an open invitation for HD4770 owners and HD4850 owners to compare benchmarks. This thread will show how these two cards performance compares and will serve as a tool to measure the performance of both cards. Rules. 1. Any 3D benchmark can be used. 2. "Hard wired" voltage modifications can be used but if done must be stated so. 3. Software voltage "tweaking" of system is allowed. 4. Any cpu/MB combination can be used. 5. Complete system Specs must be shared with each benchmark score. 6. Any type of cooling solution can be used but must be stated. If the system is in the case then it must be stated. If the system is out of the case in an open air environment it must be stated as well. 7. Important!! Any benchmark posted must be from a member of the forum. Cannot post scores from any "proffesional review". That should be enough rules to start off this thread.
