I already have a AMD Radeon HD 6850. It's been fast running and smooth and great, though as I posted in another thread, it kept doing the "Display driver has stopped responding and has recovered" minor nuisance. Given that I sent the first one back and the second one did the same, it's obviously a problem with my other hardware, incompatibility with my Peggy-tron or poor amateur installation without having first removed all Nvidia elements first.
Still, I'm wary towards AMD products despite this largely being my own problem. As such, I'd prefer a motherboard that supports NVIDIA as well as AMD video cards.
Unless the driver does the same thing on my new motherboard, cpu, and ram, I won't bother upgrading that yet, so I can afford to splurge on the CPU, so long as it's not a pointless affectation like 3% increase in speed for an extra $50.
Also, something about a board running like a scalded rat made me hesitate. Surely scalded rats don't run very well... if they're scalded enough, they might be fully dead. You meant it as a good thing?
The P8Z77 deluxes I see on Amazon are all quite expensive, more than $100 more than the regular V and LX ones, and more than the Maximus IV Gene-Z
