O and those are OEM cards apparently not for individual sale lol.
In other words I guess, GTS 150 for example in a Dell computer, and if you buy it for your custom it will be called GTS 250, atleast thats what I understand.
They are External graphic card not IGP
if some one bought GT 120 (Geforce 9500GT) wit OEM PC ...
and he decide after while to sell it.. so what he will say (i have GeForce GT 120 )or Geforce 9500GT
