Rx 480 Crossfire or R9 390x crossfire? Cpu bottleneck?

Hello folks :P 

 

I was just wondering if i'd crossfire my existing r9 390x with another but I'm concerned about the temps they produce when sandwiched to my case.

I'd really like to get a pair of rx 480's and ditch my r9 390x. 

 

I have a 750 evga g2 psu so i'd have to buy a bigger psu  to crossfire r9 390x so roughly it's  gpu r9 =369€ + psu evga 850 p2 189€ would be  558€ total

If i'd go for the rx 480 road it would be simply buying two of those so it would be 279€+279€= 558€ (Yeah I know same price as the r9 390x CF option)

 

First of, could my cpu handle rx 480 cf better than r9 390x cf?

And which one sounds better?

I'm strongly leaning towards the rx 480 option :) 

And I know there will be a slight bottleneck either ways but I want to know if the cpu could handle 2 gpu's and produce playable framerates 

I'm not getting a single card solution

I don't like the idea of Crossfiring on a mid tier CPU. You are not going to have a good time, a single R9 390x is as far as I'd go on a 4460.

Well the 390x is better. The 480 currently has thermal issues as well, and you already have a 390x so I'd probably go with another 390x since you might not have to upgrade the PSU (it would be cutting it close but you do have a G2 so....), either way the 480 isn't really better than a 390x so yeah.

I'm also planning on getting a new cpu but that's just a thought of mine :) Just wanting to know if I'd be able to crossfire with the setup I have now.

A bottle neck will not prevent you from xfiring it will however cut performance a lot.

You possibly could, but I wouldn't recommend it. I wouldn't recommend Crossfire unless you have the current gen top tier graphics card.

Any ideas how much would the i5 cut the performance from the rx 480s cf?

I haven't a clue, also it would vary game to game based on how physics/cpu intensive the game is.

So I did a little more research and I think that yes there is a slight bottlenecking (the one I don't mind) as I've read that people have used the i5-4460 for 980 sli and r9 290x crossfire without noticeable bottleneck :)
