Thinking of upgrading my gaming PC

[treebearhunter]

I'm on a bit of a budget so I can't really buy anything too expensive , might be able to get a better motherboard.


What I want to upgrade too:

Athlon 2 x4 750k Overclocked too 4Ghz
2 7870 oc 2gb in crossfire
8gb 1866 DDR3
3x 1080p monitors
ASrock FM2A75 Pro4-M Micro ATX

I have a couple of questions, so rather than start new threads I'll ask them here.

Can the 750k handle 2 7870s in crossfire?
Is 2 7870s enough juice to game on 3 1080p?
Also I have a Corsair CX600 power supply just sitting around, but I'm not using it at the moment because last time I had it in a PC my Motherboard died(had a fried electronics smell), I'm worried about using it because I can't afford to have it ruin parts, is it possible that it was just a faulty Motherboard? Is it still safe to use that Power supply? I have done the black wire test to see if it still works(It does)and it has no obvious signs of damage and there's no fried electronics smell...

That's probably enough questions for now.


P.S
I mainly play World of tanks, War thunder and Borderlands 2 but I'm thinking of getting some more demanding games like Skyrim.


Just realized this might be in the wrong category =/
