Conclusion:
Windows Vista with Service Pack 1 is a step in the right direction. Gaming performance increased in comparison to a fresh installation of Windows Vista. Windows XP SP2 provides better overall performance, and remains the place to go for dual-GPU solutions. Windows Vista is not quite the ideal gaming platform yet, but the new OS is getting close to dethroning Windows XP.
Fica aqui um comparativo feito pelo Gamspot, relativamente à performace em gaming dos novos GPU's no SP1 do Vista vs XP SP2.
