At 1280x1024, the resolution we consider to be the GTO's sweetspot, it scores around 12% higher than a Radeon X800 GT 256MB card, around 25% more than the cheaper NVIDIA GeForce 6600 GT, and around 13% less than an X800 XL.
That trend continues as we add 4x Antialiasing/8x Anisotropic Filtering into the mix. ~2,900 marks at 1280x1024 4x AA/8x AF bodes well for a £125 SKU in the games to come.
