Can't decide...need some buying advice please

[HiTi]

I am currently running 2 6870's water cooled in crossfire on a 27" lcd(1920x 1080) along with a i5 2500k,8 gb ram and one m4 128gb and a thermaltake 1200w psu atm,
I want to upgrade something....but actually want to see or "feel" a difference.
I only play BF3(min 60fps on high) or bad company 2 and other then that the computer does nothing else....although I wouldn't mind getting into folding.
Also I have a p67 board (msi gd55b3 i believe) so If going to a Z68 board would be better..then maybe thats the way to go?
So I guess what I am looking for is some advice on which way to go...large single card water cooled? or invest in another psu

Personal opinions and experiences would be appreciated
Thanks everyone...

And Happy holidays to all

Mechanical keyboard and a nice gaming mouse/pad, I would swap out the PSU before any upgrade myself, I don't trust thermaltake PSU's.

I'm covered on the keyboard and mouse...I think I have 3 or 4 different sets of various manufacturers.
I never felt warm and fuzzy about the psu since I got it, it works fine but it's just one of those things that was always on the back of my mind. Looking at some corsairs,silverstone,seasonic and a xfx now.

get an AX 850 and then you'll feel warm and fuzzy

AX 850's are notorious for coil whine...
for your system i'd grab a seasonic X850, no fan until 20% load, and just better quality then corsair inside and out.(also, guaranteed warm fuzzy feeling if you are a PC nerd like I am, just installed an X750 in a PC)

Seasonic X850 and Corsair AX850w are one and the same, just like the X750 and the AX750w, btw... I have the latter in multiple rigs here at home without a single issue.
The TT 1200w is a very good PSU too, I would not change it.

To the OP, you have a fine rig. I would not change a single component - except your HSF? Are you stock, or running oc'ed? GPU-wise, I don't understand why you only hit 60fps on high running that resolution with BF3. I run dual 560s (non-ti) on an U2412M on Ultra, and I hit over 60fps...
