I had windows XP and it had Pixelshader 3.0, I upgraded to windows 7 and update all my drivers and the Gpuz says it has pixelshader 4
I would say go for a better card xD but yeah supports pixel shader 3.0 and pixel shader 4.0 ^^ well that's according to nvidia's website.
According to Nvidia's website it supports 3.0 and above.
It supports Shader Model 3.0.
As a fraction, 8400 = 8400/1
8400
55% of 8,400= 55% * 8400= 0.55 * 8400= 4,620
2.5% of 8400 = 210
8400
8400
There are 35 240 in 8400
8400/5=(8400/10)*2=840*2=1680 . So 5 "can go into 8400" exactly 1680 times.
60 seconds = 1 minute so 8400 seconds = 8400/60 = 140 minutes. Simple!
