Recommend Sinlge GPU Please

[kPATm]

So I just got my new(ish) rig built

i5 3570k
Maximus IV Gene-Z/Gen3
8GB DDR3
SLi GTX 460 1gb

Now as you may know the Maximus has no spacing between the 2 GPUs when they are in SLi so it gets rather toasty and loud (top GPU hits around 80c bottom GPU around 70c)

Im thinking of going the single GPU route. I have been told that the HD 7950 or a 660Ti would be a good upgrade from the 460's is this correct?

What model of either card is recommended?

I am leaning towards the 7950 as it has 3gb VRam

Are there no unlocked voltage models or can the voltages be unlocked?

I was looking at that or the MSI version

Just how much of a difference would I see with a 7950?

Why didnt I think of that. Im sure I had £900 lying around

(though I think your 460 sli temps are not bad at all)

So 80c+ isnt too high then

That thing is a Monster

Hmm no point in buying a single GPU to cut down on noise only to find its just as noisy as my SLI setup?

How is the Gigabyte Windforce for noise considering it has the triple fan setup?
