So I was thinking about getting a second HIS IceQ 7870. But I have a couple concerns.

Now, I would need a new mobo that supports crossfire.
But the big question I have is if I have enough room in my case.

The case I have is an AZZA Armour case which I believe is a mid sized case.

Does it have room for 4 expansion slots? Look on the back and count. If it does, it is fine. However I kinda have to advise against getting a new motherboard for just crossfire. The R9 290 is twice as strong as your 7870 and it would cost the same or less than a new mobo + another 7870. (And be far more reliable).

1) The 290 is $300

2) The 290 will crush your 7870's and has double the video Ram. Yes it costs $20 more, but that $20 gets you A LOT more of everything and is WAY easier to swap.

Would a Corsair CX600 be enough?
I also read some of the reviews and some are saying it's a big card and requires a full sized tower. I'm curious to see how it compares in size to the 7870.

Your 7870 is huge! Almost 12" long, I know that your 7870 is slighter longer than a Gigabyte Windforce 3X R9 290 :p

I think I'm going to wait until Black Friday to decide what I do. The R9 series got a huge price cut due to Nvidia's new 900 series prices so maybe the prices will go even lower ;)

Or.. maybe I'll get lucky and be able to pick up a new motherboard & 7870 for cheap.
