you know that quadro aint mean for gaming right? and the "gaming" quadro that equal to maintream gaming card usually cost sky high....
no..no way...even you're manage to overclock it up insanely high it still won't help much. consider quadro "nvs" 140m is only equivalent to 7100 gs or 6050 and that "nvs" is probably the lowest end of quadro series you can possibly get...
result, get yourself a better gfx like 5670/gt430 or above will make huge leap in gaming experience, even though they're still weaker than 9600gt.
