what GPU will fit in dual xeon S5520UR Motharboard?

I Tried installing a GTX670 but the PCI slot would not match with the GPU.

That motherboard needs a riser card to convert the large expansion slot into standard slots.

See chapter 6.7 in the users manual -- http://download.intel.com/support/motherboards/server/s5520ur/sb/e44031012_s5520ur_s5520urt_tps_r1_9.pdf

it says riser card J4E1 as the reference designator?

It will be an actual circuit board. If you read the manual I linked to, you would see Intel part numbers in chapter 6.7.2
