I was going to build an AMD box, but Micro Center has an i5 2500k for $160, and since that is lower-power than an AMD... I thought I could save some money on the power supply and have it go to the processor!
CPU i5 2500K
Cooler Coolermaster 212
Motherboard ASRock Z77 Pro 3
Memory DDR3-1600 Corsair 8GB
Graphics Gigabyte 7770
Hard drive 1TB Seagate
Case Corsair 300R
Power supply Earthwatts 380, 350, or Corsair CX430
DVD drive Sony
Cost after rebates, without Windows: $632
I know the 7770 is going to be the bottleneck, but it's 80W, compared to the 150W GTX 560SE, or the more powerful Radeon 6850 (127 W). So, compared to either, I can get by with a 50-70 Watt lower power supply. Plus, my current monitor only supports 1680X1050, it should give me great FPS at that resolution.
Likewise, the i5 2500k is lower power than the AMD units, and I probably won't go too wild with overclocking, maybe just pushing it to 4 GHz with no additional voltage. Well, I suppose at some point I'll have to see if I can push it to 4.4. or 4.5 GHz with extra voltage, but I don't think I'll run it that hard in general. Heck, It'll be much faster than my current single-core AMD even at stock speeds! But, I can't help but tweek some...
Micro Center doesn't have the Earthwatts 380, they have a 350!! Is that enough for me with an overclocked 2500K and a 7770? I see Tom's has a 2500k build with a 650-watt power supply and dual video cards, just one of which takes more power than the 7770.

That's 166 watts at CPU load, 214 overclocked... 387 cpu/GPU load, 486 overclocked. Take out one of those GTX 460s, and reduce the power of the other to 7770-level... what size power supply do I need? 430? 380? even 350? I don't anticipate 2 video cards, ever, so I don't need excess capacity. And, I don't want to pay $100 for a 650 watt power supply when I can get away for less than half of that.... maybe! But, I don't want to use a 350 watt power supply where a 450 one is required. I like the Antec supplies, because I think they are solid, but the Corsair 430 has me worried. They are rated at a lower temp level, and my room doesn't have AC, so it does get into the 80's during the summer. Otherwise, that looks like a good (but inexpensive) power supply.
