Testing:

Testing the PowerColor HD 5750 is done with a barrage of tests consisting of these games in order: Far Cry 2, Crysis Warhead, Darkest of Days, Call of Duty: World at War, Warhammer 40,000: Dawn of War II, Batman: Arkham Asylum, Resident Evil 5, and Left 4 Dead, then with the benchmarks 3DMark 06 and 3DMark Vantage. The results are then graphically represented next to other competing products with somewhat similar performance. Afterward, an overclock is attempted and the batch of testing is then repeated and also listed on the graphs. All system settings are the same for any graphics card, except for disabling PhysX for the nVidia team on tests like Vantage.

PowerColor PCS+ HD 5770 940/1200

All of the testing was done with the PowerColor HD 5750 overclocked to 755MHz on core and 1190MHz on memory because there were some problems at first; eventually I got the card to run stable and cool at 940MHz and 1200MHz on the core and memory, respectively. With the fan locked at 100% the noise was audible but still fairly quiet - nothing like the blower motors on the 5800s. Temperatures usually remained under 55C with the fan locked at 100%, except when I went for max OC it almost made it to 60C for a short term of poking around unstable overclocks. A little over 1200MHz resulted in decreased performance and not much further than that the memory would bug out completely. The core overclock was remarkable, a whopping 240MHz gain - nearly 35% - while the memory was lackluster. The lack of stream processors was made up for by the clock speed.

Some testing was done with 940MHz core and 1200MHz memory, which was achieved at the last minute after testing with the mild overclock of 755MHz and 1190MHz - the bigger boost was achieved by trying different drivers and AMD GPU Tool software. With enough toying around the barrier was breached (Catalyst seemed to be interfering with the overclocking) and a stable boost to 940MHz was possible. The results are put in rather unorthodox but are posted below for the 940/1200 results since I was unable to test the entire suite of games/benchmarks in time.
