Ok, I've decided on the Gigabyte GA-X58A-UD7 motherboard. It's the only decent USB3 / SATA 6GB/s board that's already out, and I'm tired of waiting. $2136 unspent in budget, subtract $355 for the board, leaves $1781.

I'll order a Radeon HD 5970 and hope that I get one of the next shipment that Provantage gets. Subtract another $626 leaves me with $1155.

I'll go with 12 GB of G.Skill PI series memory, 7-8-7-24-2N at 1600MHz and 1.5V. $367 gone leaves me with $788.

I'm starting to think that I bought too much power supply, sigh. Ah well, hopefully it'll last for years.

Now then... cooling for a Corsair Obsidian 800D case for a cpu, chipset, and graphics card, for $788. Wonder if I can do dual loop water cooling for that much?
