If you want dual graphics now; R7 240 and R7 250 are good choices in both DDR3 and GDDR5 form.
While if you want a superior dual/tri/quad/octo amount of graphics later; any quantities of R7 240, R7 250, R7 260, R7 260X, R9 290, R9 290X can be used.
What must be satisfied;
16 GiB/s and possibly higher aggregate bandwidth.
A XDMA unit.
DirectX 12, OpenGL 5, Mantle.
Going into compute there is less barriers than the graphics end of things. You could in point have one Kaveri powering eight 290Xs while mining cryptocurrencies or other compute related tasks. The compute component can be done right now if you have the know how to exploit the XDMA units. It operates if I understand the XDMA units purpose much like coherent Hypertransport links.Edited by Seronx - 1/16/14 at 2:36am
