Adding another 5850 (or 5870)

So I want to prolong the life of my current rig (single 5850) and I'm thinking about adding another card to my setup; would a 5870 work with a 5850 though? I'm considering one instead of another 5850 due to the negligible price difference.

Also, as a newbie to crossfire, is there anything I need to do/be aware of? Would a 650w Corsair PSU be suitable for this? I'm running an i7 920 @ 3.8ghz.

I've heard of 'microstutter' countless times over the years, is that still an issue?

Thanks :D

What mobo do you have?
If I were you I would get another 5850 for the money, overclock and crossfire them! If it's an HX650 that would be more than enough to power it! I have two 5870's in crossfire, an i7 920 @ 4GHz, shed loads of fans, 3 HDD's and I'm only showing 561W at the wall on furmark! I have had no experience of microstutter on my rig anyway! ATi drivers are very mature for the 5xxx series now, with crossfire profile updates every large game release, can't really go wrong for £100!

I have a Rampage II Extreme. Went way over the top when building the rig.. especially as this board supports 3 way SLI/crossfire and it hasn't seen more than one card in the two years that I've had the thing! :o

My PSU is a TX 650w.
 
I think I'll go for the 5850 twin frozr on the overclockers site then, as I do value a quiet-ish system. I'll need to rearrange the internals though as the PSU is bottom-mounted in my HAF 932 and that will result in very little breathing room for the cards if I try to cram another in there. Luckily there's two PSU mounting points in the case.

Thanks! :D
