i'm looking to add another another card to my measly one r9 280. is there much difference in sols between a 470 8gb & 480 8gb card?

RX470 ~160 H/s
RX480 ~175 H/s

Claymore v7, intensity setting (-i) 4

Not too much difference yet. 470 is cheaper and more efficient than 480.

Thankyou for that. I was thinking the 470 seems to be more cost effective at the moment but wanted to double check. I will be replacing my 280 so will a 550w PSU be enough or should I upgrade that as well?

That PSU will be enough for the 2 cards.

And you can save money on the 470 if you choose the 4GB version. Nearly 0 difference in hashrate.

I'm running 4xRX470 with a 650w psu, using 450w @ the wall

Edit : with -cclock 1100 -mclock 2000 -cvddc 875 -mvddc 900 -tt 60 , and getting 140H/s per card

That is 450W for the 560 H/s. Or 0.8J/H. That is very efficient and more efficient than most CPUs as I can see.
