Gfx for pci-e in Lenovos advanced docking station

[eyeland]

Current setup:
Thinkpad t61,win7, advanced dock (with firegl v3300)
As I recently burned the firegl3300 I am now looking for a new and cheap gfx. Thi sis however easier said than done. After spending days on the lenovo forum I am still unsure of how to find a suitable gfx in the low-end.
Assumption: Though the Pci-e slot on the dock is physically x16, electrically it is only x1 (this can not be modded 🙁)
Question: In theory, what will perform better? a x1 or a x16 card?
I am looking at 2 different brands of radeon 4350, one is x1 , the other x 16. Any sense in assuming that the former one has been optimized to x1 and thus that it should outperform the x16?

Definitely an x16, since it allows for more bandwidth, unfortunately, you won't be able to maximize such a card on your x1 port.

so my question essentially remains the same, if the dock only supports pciex1 is there anything gained at all from buying a x16?

Is there a price difference?

hmm tuff to say, only found 1 pcix1 card in my pricerange and 10 pcix16.
different manufacturers so hard to say if there's a pricedifference, but I'd say that the pcix1 is a bit more expenssive.
