I would get the Asrock z68 Extreme 3 Gen 3 motherboard and redirect all the money saved towards the GPU. Something like the Radeon 7850 or even the gtx 670 if you can afford it.
Thanks that sounds like a good idea, I realize I probably won't need all the features of the ROG mobo.
But I've read that the Z68 chipset has some issues with my particular SSD.
Is that correct or have they solved that issue?
