It's pretty much AMDs single GPU flagship vs nVidia's not quite highest end card, but is so fast that it's practically equal.

I should note that I'm from Australia and can't buy off newegg, it costs a good $100 extra for the 4GB 670.

Both can be bad, I get random driver crashes in Technic Pack Minecraft with nVidia. So, HD7970 would be best?

Hmm, I'll take that into consideration after I've heard from some HD7970 owners, the GTX 670s are a good $100 more each ($200 total) than I want to spend but if they're that good then I'd go for them.

Considering the only really graphically intensive game for now (This rig will last until 2015 for Skylake, etc, but I don't want to guess off future events for obvious reasons) I'll be running is Skyrim with STEP, would I be best off with 2x HD7970 3GB or 2x GTX 670 2GB? I'm on a 1080p monitor but will go for 3x1080p monitors, maybe in vertical instead of horizontal (For 1920x3240 instead of 5760x1080) but that's yet to be decided, which card would be faster taking the recent HD7970 crossfire in Skyrim improvements into mind? Both cards would be watercooled and probably heavily OCed if necessary. The main reason I ask is that the GTX 670s would be a little faster in terms of shader horsepower, but the HD7970s obviously have the vRAM advantage which (Running a 1.2GB card now) I know is important as hell for Skyrim.

While I'd call the smoothness increase minimal at best for anything capable of running STEP, the 8GB memory stick issue is actually quite real after some quick searching. Didn't know about that, sorry.

Mainly for one page https://wiki.step-project.com/Guide:Skyrim_Installation]here[/url] Vista x64 is not buggy, it's in fact based off close to the same platform as Windows 7. You even use the same drivers. The kernels are practically the same, and none of the support software (ie. notepad, explorer, etc) are any more or less buggy than in W7.

Not if you turn off those components :D Most of them are silly safety and compatibility stuff, who needs that. But yeah this is not a path for the feint of heart, bsods will occur, its just how often. And you can create a RAMdisk for the swapfile if you have 32GB of memory which is my plan, all to fool the silly operating system that can't use it all but thinks it needs more and more in order to function.Good catch stopping I was thinking aloud about my own build while giving tuning advice, not a good combo, wouldn't want to be responsible for that mess. I'm yet to get any BSODs without a pagefile, the only issue I get at all is Battlefield 3 crashing if it runs out of vram. I recommend only 1GB vram if you have 8GB of RAM or above (For safety reasons) and 2GB with 4GB RAM, and none of the C:\ drive. Any BSODs already give you a code that lets you work the reason out easily. Anything more is just a massive waste, I tax my system hard with multi-tasking (Right now I'm at 6GB RAM used) and I've never needed more than that.
