I would like to crossfire the cards, but i would settle with just having the 6870 run solo. Im aware ill have to upgrade my power supply probally, any suggestions for solo 6870 and for if i did crossfire them?

unfortunately, you can only run CrossfireX with two identical cards, but your system SHOULD be able to handle the single 6870 with no problems

Aww well thats ok, i wouldnt need a power supply upgrade??

a 500w power supply would work, but you should still upgrade it just to be safe, but for the time being, 500w is alright.

500w is the bare minimum
