I played CS since it was in beta around 1999 and at the time I was poor and living out on my own with a POS AMD athlon K6-3D 450Mhz CPU 128MB SDRAM and a ATI 3D Rage Pro 64MB AGP. I was averaging 20-35FPS and sometimes hitting 60FPS when I tweaked the death out of the Goldsource engine. I still played well enough to win a spot on a CAL-Main team and average a positive KD on matches and pubs SO as others have said, SKILL is the greatest weapon although more FPS helps.
