Everyone's suggestions were great and I just wanted to add what I found too, here is a link to your docking station with part # 45N6681
here's the link for your part # 45N6678:
both state that they are compatible with T420 and T520 duel core models.
I hope this helps you,
ThinkPad Advanced Dock comes with One half-size PCI Express card slot - Supports half-size PCI Express cards, including graphics adapters that enable multi-monitoring. The ATI Radeon HD7750 is a full size PCI Express 3.0 x16 bus interface which unfortunately wont work in the docking station. Here is the link to ThinkPad Advanced Dock:

The PE4H is a great idea to use a PCIex16 card with a notebook could you just let me know more about what you want more info on? For example does the PE4H work with T420? More workarounds like PE4H?
