So, this is my first high-end processor, and my first OC attempt. I'll have help with the actual Overclocking process, however, I need to know which motherboard I should go with? I've been told that I'll probably have to go with a (if I stick with AMD, which I'd like to) 790gx, or fx, chipset motherboard. Past that, I'm lost. I had been mulling over crossfire, and for that I would probably want a board that can support atleast 2 PCI-E 2.0 slots at 16x speeds, but, does that really matter, say, If I'm running 2 4870's?
I have the MSI K9A2 Platinum, and it works wonderfully. It does support 2 x 16x GPUs I have reached 2.9(on my 9850)with minor voltage and multi tweaks. MSI does make a really nice board, and is affordable. I suggest the FX chipset, but thats just me. The AMD Overdrive works with the x or later chipsets, which makes OCing a breeze.
