At $499, the GTX 580 competes strongly with ATI Radeon HD 5870 Eyefinity6 2GB video cards. We considered adding the Radeon HD 5970 into our review, but at the time it was fetching a $660 cost. As of yesterday, we are now finding one HD 5970 for $499.99 so surely we are already seeing the GTX 580 have an impact on the high end video card market. And of course this change in price demands a new comparison review from us.
[H]OCP Review of GTX580

I don't see the logic in his statement. Wait, let's see, he tests using and AMD Eyefinity6 2GB card which he never really even uses the 6 screen output and the extra 1GB is most likely giving a 1% or 2% better framerate(if at all in some games) and then compares it to the $499.00 GTX580.

Um, hello, why compare a niche E6 5870 when its not needed. I know why, so he can say the GTX580 and E6 5870 are evenly price matched.

He should have used a regular HD5870 which can be had for $300 ~ $320.

And he leaves out the 5970 in which he claims was just recently found for $499.00 but was somehow $660.00($160 MORE) just a week ago or so when he was testing the cards. Sounds like BS to me.

So basically what he was doing was testing a $320 card to a $499.00 and claiming they were evenly price matched. Sorry Brent, you lose!
