What wattage PSU would be recommended for my new build?

I am using a Kingwin Lazer 1000 watt 80+ Bronze PSU for my current build, though it lacks enough 6+2 PCIe connectors for future GPUs. I did feel as if my current wattage should be enough for my future build, though those PSU calculators suggested anywhere from 900-1200 wattage.

I am dead set on getting the Asus Crosshair V Formula-Z motherboard with the AMD CPU. So those are the only two things I will get for sure.

I already have a blu-ray player, so that's not something I can cut the cost down on. I do already have Corsair Vengeance DDR3 1600, though my motherboard can take advantage of an OC'd 2400 mhz. Any suggestions on the RAM, would definitely be appreciated. As I do know the improvements are not devastating, though it is noticeable.

As far as the GPU goes, I would rather have a dual graphics card set-up as I am definitely someone who likes to play with details as high as possible. And will go into the .ini files to manually configure graphics to the absolute best balance of performance vs. detail.

After scouring the internet for months and talking to friends who have one, I have decided on getting the HAF 922 case for it's reliability, features and airflow performance.

And with the SSD. I would LOVE to get a SSD, though why I'm not ready to upgrade to them yet is the average lifespan not being very long and with games requiring much more space now-a-days. I'd imagine that even if I bought a 500gb-1tb SSD, that I would be buying a larger one in a few years anyways. And the high price tag I would pay now, would be a slap in the face when I go to buy a larger capacity SSD. I play a variety of games, though the only games I own that will take advantage of an SSD is BF3/4 and SWTOR (which I semi-regularly play). Basically, I would really only take advantage of an SSD for my OS.

I am primarily a gamer and I do contract game testing for EA, Activision, Ubisoft and Sony. I got passed up for the BF4 Alpha because they had already filled the quota for low-mid range builds. My current build was put together in 2009 and was on the mid-high range scale. The only other thing I use my PC for is music production and school work. So as far as demanding apps goes, it will be for gaming first and audio production second.

Thanks for the help on this! I came in for help on PSU wattage and got some good advice on the rest of my build.

I'm going to continue to use my Kingwin Lazer 1000 watt until I upgrade my GPU's and that way I'll be able to more accurately match those two components up.

I'm going to just keep using the Corsair Vengeance 1600's that I have now, though I would like to upgrade from 8 gb to 16gb. I know with my motherboard, I will be able to set the two modules in the outer DIMMs and that will place them far enough away from the CPU cooler.

I'm going to wait for the custom 290's to come out and see how the perform and use my dual 6850's until then. I really want to upgrade my GPU's, but after deciding that I wasn't going to be getting into the 4k monitor market yet. That dual 280x's would be just fine. However, I really want double ROP's and 512mb bus. So I guess I can wait for the custom 290's and buy 1 of em. Hopefully that'll give me better performance than the dual 280x's.

I'm downgrading my 2tb hdd to 1tb and I'm gonna get a 250gb Samsung Evo SSD. I know I didn't need the 2tb capacity, I was just buying it due to the price being only around $50 more.

As for my case, I decided to change it to the XM. I liked the bottom intake fan on the 922, though I don't know how much advantage it truly provides over the XM's dual HDD cage fan set-up.
