I would think, because your older generation motherboard wouldn't support much bandwidth outside the first pcie slot. So, the original 580 would have a bus speed of 16x, then the second would be at 4x, or 8x. Maybe not, though.

Actually one of the reasons I picked this board is because it has dual x16 lanes in crossfire/sli.

Haha though lately it's looking more and more like SLI with my config is a pipedream.

You should be fine with that chip, but you will have to push it to 4.4Ghz which tends to be pretty hard given the voltage that is needed

Yeah, I'm working my way up to that. I'm fairly new to overclocking, and my main goal is to get my FSB up to 400, since my RAM is 1600MHz but only running at 1400 something right now. Coretemp says that I'm getting up to 56C on air at 4GHz with Prime95, so I'm not sure how much further I want to push it.

You'll have to grab something to disperse the heat more efficiently than the hyper 212+, great cooler for the price though

Thanks for the input. I did create a thread in the power supplies forum, but haven't heard back yet.
I meant no disrespect at all. I'm still rather new here, and honestly had no idea who I was speaking to. If I seemed dismissive of his advice, I apologize. I just didn't want to throw the baby out with the bath water.

Whats going to happen is when you play games on the gtx580 sli on the c2q all your going to see is 50-60% usage on both cards when they should be 90-99% for the most part. Its a combination of the CPU design and Mobo design. The pci-e lanes and Memory controller are routed though the FSB to the CPU and the FSB is one of the limiting factors on the 775 platform. Its not that the C2Q works better with AMD but that it works better with just a single card. You setup just can't handle more then one card efficiently. You can use a GTX680 or HD7970 and be perfectly fine for the most part, but once you stick two higher end cards onto that board all you will get is a massive bottleneck.

I once ran a 4870 CF on my ud3p board with my q9550 @ 4.2ghz. I never had a single problem with scaling or drivers.The GTX580 is more then twice the GPU power so to have two running in SLI and expecting the same results would be taking it pretty far when it barely was chugging the 4870's along.

I think you still have to have CPU and or chipset power to Handel the dual x16 lanes which may be or not be why it would bottle neck more with CFX or SLI. Also that DiabloTek is a death warrant.
