Regardless of what fanboys say, the charts tell the real story.
Your PSU should be fine with a GTX 470. GTX 470 power consumption with a OC'd Core i7 920
The GTX 470 is showing some good numbers for DX11 which is a good sign when you're thinking about future games.
To me it looked like the GTX 470 edged out the 5850 when AA/AF, SSAO & Tessellation quality settings were turned up.
Thats a good thing for gamers who like the 'eye-candy' settings.
You might need to wait 24hrs or so to see tracking status on the NewEgg page.
Might catch a glimpse of the movements sooner on the USP site.
I've never been impressed by the 'fastest' claims. I want to see which one is 'not slower' in the minimum frame rate.
I'd be willing to take a lower average FPS if the minimum FPS was higher, especially if the average is 40+ or higher, and smooth.
Remember, your mileage may vary. Look at all the charts and try and figure out what is going on in your games. If you're not playing Game X - what does it matter that this card or the other is faster? Try and pick out trends in future games (like DX11, SSAO & Tessellation and the like) if that kind of stuff interests you.
But at the same time you can be banking on significanly better performance while it my be the trends show that over time you'll get better performance with drivers you don't know how much of that happened while the development phase the recent 197 added quite a bit of performance so all I'm trying to get across is it's an uncertianty
They're getting pretty good overclocks out of GTX 470s too.
First two charts are at stock - last two are OC's. (You can click the chart to get the article)
It's interesting to read what AnandTech says about minimum frame rates here - same article you linked from.
I'm still trying to make sense of some of the dueling chart results but I think this pair
goes a ways toward showing something of a trend.
Higher 'eye-candy' settings in chart 1 - higher 'twitch' gaming in chart 2.
