By "visual rendering" do u mean photo/video editing? Double check if your app/software of choice takes advantage of GPU acceleration 1st before pulling trigger on GTX 460 SLI Audio encoding is 100% CPU btw
If you want a spec for video and audio editing/rendering :
-For rendering only, you can go down to GTX9800 for the GPU.
-If you still can afford it, more RAM is preferable, if you try to process HD videos, than you will know the real use those RAM.
-Multitouch thing is not my thing, you can drop the multi touch thing and get a monitor with better color room. You will need the color room more than you need the touchy touchy thingy.
-Find better PSU for example from Corsair.
ok its not for studio its for live performance. So i believe the multi touch will have some advantages. Also you referred to GTX9800 but i really go for 2 * gtx 460 because i need some massive parallel processing.
I am a bit concerned about the energon psu. It has only two pci-e connectors, sufficient for one GTX460, but not two. The power looks ok, and you could always use adapters.
It is not a brand that I am familiar with, so research it carefully.
Personally, I would stick with Seasonic, Corsair, XFX, PCP&C, or Antec to name a few.
I would go with the XFX 750w unit: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
There is a lot to love: silver certified and modular.
I think you may want to add a oem cpu cooler up front when it is easiest to install. It will let your cpu run cooler and quieter under load than the stock cooler would. If you want to overclock a bit(and the 930 is an easy 3.3), then your overclock will be easier. You should be able to find a large tower type cooler with a 120mm fan for <$40.
As I understand it, lots of ram is most helpful to your uses. Consider a 12gb kit(3 x 4gb). That leaves room for expansion. Today, there is only a small price premium on 4gb sticks vs 2gb.
