The most important results are the game benchmarks and this is where Sapphire Radeon x700 Pro pulls out a 6% advantage over MSI GEFORCE 6600 GT. There was some game results which clearly show that certain games favour either ATI or Nvidia but overall Sapphire Radeon x700 Pro and MSI GEFORCE 6600 GT both delivered playable results with ALL of the games tested!"
COMMENT "Using core speed, memory speed, pipelines and memory interface of each video card we can work out the theoretical performance of the video cards. MSI GEFORCE 6600 GT theoretically should outperform Sapphire Radeon x700 Pro by 8%, Powercolor Radeon 9700 Pro by 33% and the Leadtek GeForce 6600 by 40%. Ofcourse theoretical performance of a video card can be effected by the motherboard performing better with certain types of video card, we have found that motherboards using ULI chipsets usually favour ATI video cards which has to be taken into consideration."
