Maybe, however I wouldn't recommend the X1300 and the X1550 is also pretty weak, but they are both available in AGP variants.
Considering the crippling effect of the PCIe to AGP bridge, even the X1950Pro doesn't come off that good.
The 3850 or 4650 might have enough GPU power to compensate for the slow transfer rates...maybe.

In any case, right now I stick by my recommendation of the three cards I mentioned.
