I currently have a SRAM gxp press fit BB installed along with SRAM gxp cranks.

All these bb standards are causing me a bit of a headache now I need to replace it.

Can I fit a shimano press fit bb like the one below? Pretty sure the axle will be the same diameter but not sure how my current SRAM one will seat up against the bearing the same? Please help...

Can I fit this:

Shimano use a 24mm BB axle whereas SRAM GXP axles are 22mm...

See this: http://singletrackworld.com/forum/topic/sram-gxp-bb-incompatibility-with-shimano-ht-ii-cranks

You can get an adapter for your King BB I think.

Weird - was the OP edited, or did I skim read and just click on the Sram one???

As above, you need a specific GXP compatible BB or a step down reducer for the non drive side.
