I vote for EVGA for the warranty and 24/7 customer support. I got my RMA at a 11:30 pm central time. I was quite pleased with that for some reason.

You've been saying 570 SLI would be faster than 6970 CF in another thread aswell which simply is not true.
Go check some reviews and get your facts straight.

single HD 6970 is already faster than a 570 and CF scaling is way better than SLI aswell:

Even 6950 CF is faster than 570 SLI sometimes, especially at higher resolutions.

Not Fermi, Fermi is very innovative.

The issue is the 590, not even compared to the 6990.
It should be compared to the GTX295 as far as innovation is concerned.

When compared to the rev 1 295, even though it was a dual pcb card.
The 590 seems to me that it's a simple rehash of the rev 2 295 co op, which paled in comparison to the rev 1 295.

The rev 1 295 was pretty much bomb proof, massive amounts of oc headroom. Heck I ran both of mine at 1.18v 738/1476 for months with nary a hiccup, f@h.

Capture-2.png

That is what I expect from an enthusiasts card, so do many other people.


Look at the NF200 bridge the 590 is using, that's been around since the 9800GX2, nothing innovative there.
While the CFX PLX chip has been changed 3 times since it was introduced in the 3870X2.

My point of view doesn't even involve the 6990.
It's the downward spiral since the rev 1 GTX295 that bothers me.

Heck a dual pcb version of the 590 may have done better.

How would a dual pcb solution fix the VRM problems? The 590 simply suffers from an insufficient power circuit and could easily be fixed by using a higher phase VRM with better mosfets.

A dual-gpu single PCB design is much better than the flawed dual PCB sandwich design that the 295 Rev1 had in terms of cooling.

If you look at the 295 Rev1, due to the dual PCB design, both GPU's were sitting at the exact same place firing up the cooling block from each side.
So you had only 1 cooling block that had to handle the heat of both GPU's which made them heat each other up too (not to forget the fan that had to dissipate the heat of both GPU's at once).

Now lets take a look at the single pcb design.
Since the GPU's are placed on either end of the pcb with a center fan and seperate cooling blocks, the heat does not add up to each other and can be cooled seperately and thus much more efficient. Also since the fan is blowing 360° into each direction, each GPU gets independent airflow unlike dual PCB design where both GPU's had to "share" the same airflow (ultimatively making the fan have to spin a hell of a lot faster to achieve same cooling performance).

It's easier to cool 2x 150W than 1x 300W (just random numbers, but you get the point).

I'm not saying it will, but it worked, it was capable of overvolting a lot on air and still be within specs.
Plus with the 2 pcb's you could fit more components as needed.
I know for extreme users, single is preferred, but even those guys would want one that is as bulletproof as the rev1 295.
I'll say it it again, that card was a superhero.

It just annoys me that NV would step down on their quality with an enthusiast card such as the 590.

My impression is that the article is good.

Nvidia has design issues for some time already and they should fire some people.
Maybe the guy who showed us the fake Fermi card would be the first to go.He is still working at Nvidia isn t it ?!This says a lot about the company as it is now.
Getting cheap on the high end smells bad.

Dual sandwich PCB would of meant that each core could have it's own VRM circuits on it's own PCB.

It would of also meant more PCB space for more phases.

I was not mean at all. I was just underlining the need for a "reputable website" to stay away from expressing personal opinions and even give the 'fire the whole design team' argument when it is clear the product is the result of paperpushers and not engineers.

I have made my point.
Nobody should stay away from expressing personal opinions ,even in a review.At least untill we will all become borgs or something.
