btw to remove any bottlenecks i was considering an upgrade to a 2500k do they run hot at all? id want to overclock it to atleast 4.2 ghz but i hear they do that very easily.
Yeah your CPU is definitely overheating. And even overclocked, you're bottlenecking the crap out of those cards. I had a severe bottleneck with an overclocked Phenom II X4 using my 5970, so I imagine this bottleneck is even worse.

As far as 2500k goes, with a good motherboard you can easily get 4.5GHz, and overall they use less power than Phenom IIs so it should keep your room a little cooler.

The Pro is a highly recommended board.

Im picking on up here soon too.

Just be sure to get 1.5v Ram for it.

P8P67 Pro is a great mobo. Also check out the ASRock P67 Extreme4 Gen 3...

If you think you'll use a SSD in the future you might want to look at the Z68 motherboards (for SSD caching). If this isn't an issue, I'd say that looks like a good motherboard. The placement of the PCI-Express slots is great, as it'll give you extra space between the cards and help to reduce temperatures.

BSOD 124 is not always related to CPU when it comes to GPU OC.

If you are using Sapphire Trixx, disable ULPS as pict below. Now your Crossfire OC will work fine.

Give it a try.

Lower the memory clock down to 1375 MHz. All chips are unique and not equal when it comes to highest OC.

Edit:

Also, watch the full load temperature. Memory doesn't have temperature sensor and overheating it will also result in crash.

And run RAM test for error.

You dont need to go buying a whole new setup, waste of money.

I run 1.5v vcore and 1.4v cpu-nb, stable at 4060. I used to run 1.525 for a bit, but that was with lower cpu-nb. By upping the cpu-nb (up to 1.4 is generally regarded as safe) you can lower your vcore. You shouldnt really need 1.5vcore for 3.8ghz anyway unless you just got unlucky with your chip. I think you can tweak a bit and reduce your temps, and try get better flow through your case. Much cheaper than buying a whole new rig...

Ps. Australian here too. Reduced my voltages because of the warmer weather coming, my Trifire, clocked cpu and 3 tvs heat the room up like a b!tch!
