Introducing AMD’s “Turks” – HD 6670 and HD 6570
Serious Sam Second Encounter HD (2010) 
Serious Sam is the title of a series of first-person shooters created by the Croatian development team Croteam. It follows the adventures of its hero Sam “Serious” Stone and his fight against the forces of the extraterrestrial overlord Mental who seeks to destroy humanity. Its gameplay is a throwback to early first-person shooters like Quake and Doom with the twist of being set in wide-open environments with large groups of enemies attacking at any time, and there are many hidden areas and treasures to find and puzzles to solve.
Serious Sam features cooperative gameplay and allows for split screen action supporting up to 4 players. Serious Sam: The Second Encounter was remade as “HD” using Serious Engine 3. It was released on April, 2010 for PC. Besides updated visuals, new game modes including “Co-op Tournament” and “Survival” for single player, were introduced in this remake.
We use the basic 3 “ultra” presets for benching Serious Sam: The Second Encounter HD. There is possible further fine-tuning which will make the game even more demanding, but we chose the “ultra” presets with only one higher GPU setting, to allow for testing beyond 1920×1080.
We test first at 1920×1200 resolution:
Our settings are way too high for our subject cards so we test at 1680×1050 with the same ultra presets:
Serious Sam: The Second Encounter HD on the Serious 3 engine is quite demanding . The GTS 450 is solidly faster than the HD 6670.
great review mark! Huge piles of data, thats what i love about the abt. I totally agree with your conclusion which is spot on. Given the gts450 and hd5770 may not be around for much longer these cards should be a great option in the future but for now there are some really nice price/performance options in the same bracket and they just dont shine through them. In time they may fall in place when some of these killer deals from the last generation slowly slip out of the picture.
