My 430W handled just fine, peak load I saw was 380W with the 2600K @ 4.5GHz and the system fully loaded. I'm not even going to be keeipng the CPU at 4.5GHz, more like 4.3ish. The cooler can handle 4.5GHz fine if I let the fan spin up, but that's not going to happen. I want my silence.
I went all out and basically got the best mobo available instead of the Asrock.
Final specs are
SILVERSTONE RV02B-EW

16GB RAM is so much lol, I didn't even have a problem with 8GB (6 isn't enough though). But yeah, cheap enough.
The SSD has been nice, does what one would expect; drastically reduce loading times.

I can't be sure on 4GHz vs 3.4Ghz but you can see in the R10 chart that the 2600K @ 3.5GHz has a 160MHz disadvantage to the 920 @ 3.66GHz and has the same number of cores + hyper-threading. That didn't stop the 2600K from making an unquestionable win over the 920. I'd say Nehalem 4GHz ~= Sandy Bridge 3.4GHz is a believable claim.

The thing fascinating me right now is that not only can I run displays off the onboard GPU and the card at the same time, the monitor connected to onboard has the performance and features of the card. Dragging the Unigen Heaven benchmark between the monitors is seamless and I get tessellation on both even though the Intel GPU isn't even DX11. Someone's been working their magic to make this happen... Lucid?
