GeForce GTX 590 Key Features Revealed

on the whole switch does it invalidate your warranty argument.

link to support page

it clearly states that damages caused by using the card outside of the factory shipping setting is not covered by your warranty. so if you flip that switch and you then have problems with card your stuffed.

So if you overclock a 6990 and burn it out you are boned, like another other piece of hardware...

The switch just means you have two factory settings, flipping it is allowed but overclocking it past that is just like overclocking any other card.

Or atleast that is how i'm reading it.

6990 OC head room around 15%... GTX 590 OC head room around 30%... This is one hell of a fast card and I WANT!! :D

Considering you could get a pair of 6950's and have over £200 left over from the price of the cheapest 590. I think most would agree the moneys better spent on 2 seperate cards or a 6990.

Honest question: would you pay £100 more for one when in the US (hypothetically speaking) the pricing of the two would be the same? :)

This honestly, annoys the crap out of me. It's ridiculous how high the taxes are here, and parts ends up being so much more expensive than anywhere else in the world. Can't wait to move to the US.

On that argument, AIB's have all officially, or unofficially said it WILL NOT invalidate your warranty, so, meh.


As for overclocking headroom, people seem to be getting the wrong impression of the 4990 OC setting, which increases powertune more than anything else, meaning Furmark goes through the roof but GAMING doesn't meaning theres a bit of headroom there both in temps, noise and clock speeds. I really haven't seen any good indication of where a 6990 clocks to in games, while completely ignoring Furmark, something I've been suggesting people do for two years, its literally a useless tool, for Nvidia and AMD, it won't find you stability, it won't find you top temps in games, it won't find you anything relevant to any other software you will run.


As for overclocking, Techpowerup overvolted their card to get "good" clocks, and blew their 590gtx, he says asking several other reviewers, several other cards died with "safe" voltages for a 580gtx. They showed with non voltage changed overclocks, it went to marginally ahead of a stock 6990.


The ONLY thing Nvidia got right was the fan, if AMD put the same fan on their card, frankly it would be a no contest, better cooling, better temps, quieter, more overclocking headroom(most likely) with lower temps.


Why oh why do AMD stick with the worst ruddy fans on earth, whoever is making that decision at AMD really should be fired.

"During our briefing with AMD, we were constantly told of its efforts to make the HD 6990 4GB cool and quiet, and yet the vast majority of the comparative performance data was based on the much hotter and louder overclocked mode. Most concerning is that AMD says that you void your warranty by using the Antilles Unlocking Switch – this is a ridiculous decision considering that the switch is a standard feature of all cards."

Even Fud are reporting AMD AIB's saying they are warranting the OC switch, secondly, there is no way for them to tell if its overclocked, its largely a deterant to stupid usage. Which is better, for AMD to suggest they won't warranty it(and they probably won't, can anyone find an AMD 6990 in stock anywhere, where you go direct to AMD for a warranty?) to put people off using unsafe settings, or for EVGA to provide their card with an overvolting tool, which according to reviewers, simply blows the cards up?

Its called safety, probably 70-80% of 6990 buyers are just buying the biggest and best and don't need that power, some people will overclock just because they can, 5Ghz sandy's when the most punishing thing they do is WoW all day.

Anyway, theres nothing to suggest AMD will warranty the 6990 in OC setting, but their business is with the AIB's, AIB's can offer whatever warranty they want on THEIR cards, which THEY replace. Its irrelevant what AMD and the AIB do, the only thing thats relevant is between you and the AIB you buy from, as they've basically all come out officially, or unofficially, and legally by advertising the OC switch in most countries that means they can't refuse a warranty for being used AS ADVERTISED. Legally, basically everywhere, every 6990, from every AIB, is warrantied, its that simple.


Bit tech are getting dangerously bad, they appear to have a broken 5970, and instead of replacing it, just decide to include bad results where it won't work(yet no one else has a problem), or the 6990 inducing microstutter in the highest performance situations, where in 99% of cases microstutter in multigpu setups is induced at extreme settings when performance drops below a certain threshold, then their game choice, Bit-tech's choice seems to be the "nvidia benching prefered list" combination of making it look its best, of the few reviews I've seen, theirs is by far the best picture on the 590gtx, by far the worst on AMD and by far the worst choice of games, with loads of incredibly weird results with their duff 5970 and their microstutter only when at low res 6990's. This is ignoring the fact they keep refering to their 5970 results in the graphs as a 5990 below it.

Then again Bit-tech have a staff that manage to get half their news wrong, and do reviews on 5870 custom cooling and fail to even look at the stock heatsink to see what needs cooling, they killed their card because they were too stupid to notice another chip on the card that needed cooling.

They're calling it "the most powerful DirectX 11 graphics card ever built". Depending on interpretation, it may or may not be correct.

IMO both the 6990 and the 590 are failed cards but I tolerate that some may disagree.

I wouldn't also go as far as slating Nvidia for the pricing as they generally put a significant mark-up on their products and yet their priced their lead card at the same level as the competitor. As for the UK pricing - no comment from me. False economy really.

The GTX 590 is not the "World's Fastest Single Card Solution" as stated on our page 1 slides; the Radeon HD 6990 is very much retaining that title.

Performance is not higher than HD 6990

Plenty of other say the same. 6990 is also cheaper. Know which I would be buying if I was upgrading to this generation.
