Guys,
3500+ is abt 10500.
opty 144 will be 9 max
Opty has 1 mb cache will be helpful for him in apps like maya where he will need it.
Even a bad yield opty,suppose even if he gets it will easily do 3500+ speeds.
Iamrahul check with ur dealer if u can just get the stepping code of the opty 144 from him and google it to know how good it is.
