[citation][nom]meganfox16[/nom]There is not really a whole lot different between the two, I have tried both on my computer right now.. the 1255 actually seems slower in Prototype... about 2 FPS differences on 1900x1080. Using the highest AA. I do have all the lastest drivers. Both of them are Windows 7 Ultimate x64. Going to try testing them again on my lower computer. My system: i7 920 OCed 4GhzEVGA Classified E7593 GTX 285 SLI6GB Dominator[/citation]
Your system is very powerful and 2 fps may be a measuring error.
Anyway, the difference is very small and cannot be considered statisticaly signifiant,
Further testing is a good idea, though
