Hi, I am getting a PCI graphics card for my dell docking station. The only one I can really use is the Radion 9250. My question is, they have two at compUSA. They are both PCI 256 DDR and have the same chips, however, one has two processors I guess. One is 129.99 and the other 79.99. The cheaper one is for Direct x 8, but will it still work? I am short on cash. Thanks, jon
