Hello,
i am running a gigabyte gtx 460 soc in a p8p67 board. i only recently realised that the card has been running in this mode as i had benchamrked my system and had recieved some low 3dmark 06 score of ~12000 i am confused as to why it is running at x1. there is no other card in the secondary x4 slot and folding (gpu) produces ~800 ns/day

Newest board BIOS? Have you tried without your CPU Overclock? Make sure the card is fully seated in the slot (try putting it in again). If some of the contacts don't make full contact, you will lose bandwidth.

Also, could you post a GPU-Z screenshot of the 460?

Something is not allowing a proper connection between the 460 and the motherboard. In this person's case, it was dust. ( http://forums.nvidia.com/index.php?showtopic=191278 ) But as this is a brand new board this certainly is not the issue (and since the 9800 works).

Do you have any other computers you could try the 460 in? If not, you'll probably should return the 460 and see if its replacement works properly. The 9800 working while the 460 does not is pretty strong evidence that the 460 is some way at fault, either physically (bad PCI-E manufacturing) or mentally (corrupt BIOS, etc.).

I'm thinking something is wrong with the card itself. Try it in the 8x and 4x slot. If it still reports 1x in both then I would certainly say it's the card. If it reports 8x in the 8x slot then I would try tapping is that the 16x slots will only use 8x lanes. If it reports 8x then it would mean something is wrong on the end of the card. if it reports 1x then I would assume that its the board you need to RMA.

on my am3 rig, it shows the card to be running @ x8

could you try a newer GPU-Z on that computer (that one can barely read the specs). If it is the same link speed, you don't need to post again.

ok so i tried to use the exact same settings as my sandy rig with win 7 x64, only difference is the M/B and cpu (am3) and only 2gb ram as i didnt wanted to take off the nh-d14 cooler to access the other ram stick. this is what i found,

this tells me that the gpu itself is throttled (x8) but when inserted in the sandy its throttled further to x1. maybe its something to do with the power phases on the gpu :?
the 9800gt in the am3 with similar setup is reported as x16 so both motherboards aren't the issue

Looks to me like the card may be defective. The last possible test I can think of is to use a different PSU in the SB computer. However I would probably try RMAing the card first if they (the store) doesn't give too much trouble.
