I think you have misundertood what the gfx card does! It makes previews you dont get realtime film quality graphics with even the most expensive gfx card. Atleast not in the way mr does for you.
And yes a quadro 1400 is REALLY old its like 4 generations old. So yes it sucks nowdays you should have a x700 or x800 where x is series and the hundreds is chipset.

The problem is i cannot seem to achieve a top level cinematic quality rendering using the card compared to rendering though maya using Mental Ray.
And you wont no matter what card you buy. Not exactly the thing you think it is.
In anycase anuthing below fx 1800 is obsolete by now. Not worth the money really.
