First and foremost, I bought THIS today with the intent on using it in my latest gaming build. It's rated at 500W and is "SLI Certified/Xfire ready", but from my experience the rating is usually a little higher than what a PSU is actually going to put out. I was intending on putting a single Radeon HD 5850 as my video card as it fits my price point, but after reading the 5850 review, under a full load it's rated at sucking a little over 300W by itself (the 5830 being rated at *half* that power consumption, but that card is a whole separate demon to discuss), leading me to worry that assuming the PSU actually tops out at maybe 450W average, a little less than 150W isn't going to cover the CPU and everything else.
As for my second issue, I'm looking at two CPUs here:
AMD Phenom II X4 945 Deneb 3.0GHz 95W
AMD Phenom II X4 945 Deneb 3.0GHz 125W
From the specs, they're *exactly* the same CPU, except one is rated at 95W, and the other is rated at 125W. They're also exactly the same price. My first reaction is that the 95W one is just a later revision of the chip that consumes less energy for the same performance, but by that line of thought I would expect the 125W to be a little less expensive, or at least the 95W to be a little more expensive. I feel like there's something i'm missing between the two.
Edit: To clarify, I don't intend on overclocking anything in this system, everything will be running at stock clock rates.
