Nice. I will be interested to hear your thoughts on the card.

This doesn't make sense to you?

Why would AMD undercut themselves selling a card with 2 X 7950 performance for much less than two 7950s? No one would buy two 7950s?

The anti glare coating seems to be better on the samsungs as they're considered less grainy, as i know some complain about it on the dell U2711's, even to the point of trying to remove it, wich risks scrapping the panel( crazy to even try it i know).


The external power supply on the samsungs is pretty cool in terms of replacement should it fail...I can do it myself, while it's built internally on the Dell's, wich means shipping the whole panel to repair it.


There is a slight improvement in pixel response times with the samsung(5 Ms versus 6 Ms) and the stand on the sansungs support portait mode, while the Dell's stand doesn't, so i can do either 7680*1440 or 4320*2560 modes across 3 screens....The panels also use less power, but that's a minor thing really.


So it's little advantages here and there that add up, though the Dell U2711 does have impressive picture quality, of that there's no doubt of it, but since this is brand new tech being introduced by samsung and aimed at the same market as the U2711, and the very good review it got at that site i linked, i figure i'll be the guinea pig and try it out...



Did the forums crash last night for several hours?

Much less is a relative term here, since they's rumored to launch at 450$....The main advantage of the HD7990 is that it maintains all the shaders and texture units operational, wich some are disabled on the HD7950.


Now obviously a card like this is going to be just as much a power hog as the HD6990 and the GTX590, even more so when overclocking it so it beg's to be water cooled to keep it silent and have lower operating temperatures and potentially higher overclocks.


As for the price, it's mostly that it's been several years since we've seen prices this high for a video card regardless of brand, especially considering that the die size for the tahiti GPU's the HD7990 uses clocks in at 365mm^ and not the 500mm^+ seen with Nvidia GPU's, wich makes them more expensive to make since fewer are coming out of each wafer...

That stand alone was $200 so if you get them included, that's a big plus.

In my opinion and experience, response time is just a small factor of the whole equation. Input lag due to an image processor can add a lot more delay. The Dells (2711, 3011) don't really excel here because of their scaling ability and image processor. Most users say they don't notice it but it's definitely there. But it's not something I want and that's why I always bought high quality screens without image scalers/processors.
Not sure how the Samsung behaves in this regard but apparently it does have some soft of image processor. That would be interesting to see in upcoming reviews from sites like Anandtech or PRAD.

Although, as for the PLS panel itself, it probably can't compete with the Dell's 10 bit IPS.

I'm sure we'll see more reviews as the months roll on, and that's what we'll see compared with the Dell 2711, wich is pushing nearly 2 years since the model was introduced...

Going from that chart you would be better off waiting for the HD 7990 since it is listed for $849 and two HD 7970 would run you around $1100.I am sure the HD 7990 will overclock to 925Hz and the memory to 1.375GHz unless they make it where it want overclock.

Some people just like to get the latest and greatest. Even if it only means a 10-20% increase which you are unlikely to see in the real world. Money doesn't come into it, if you are lucky to have enough.

Keep in mind he does have a good point going, as a triple crossfire HD7970 setup is 1650$ + tax and shipping, while a single HD7990 and a single HD7970 would be pretty damn close to the same performance, even if the dual GPU card doesn't overclock as well, and save me 250$.(1400 total)


250$ less isn't chump change anymore, and would be enough to buy the water blocks for both cards, and free up an extra PCI-e X16 slot on the motherboard....That's about the main difference with AMD drivers in that you can connect a dual GPU with a single GPU card of the same generation, and still get triple crossfire working that way....It doesnt need to be 3 indentical cards....Do Nvidia drivers allow to do the same thing?

Ive read a few reviews on the HD7970 and have to say considering that it is AMD's 'next gen' GPU i am not impressed at all.

I am in the market for buying a new GPU this year and considered going the AMD route. Thing is i passed up the opportunity to get a GTX580 for 300 a few weeks ago...Holding onto the thought that i would stick to my guns and purchase a next gen card in 2012. I definately will not go AMD route as an average of 7fps in most games just doesn't justify the 480 price tag that comes with it, i would sooner fall back to the GTX580 for 350. I eagerly await Nvidia's flagship card though as i know it's gonna destroy this AMD card in every benchmark...

It's got no choice and has to do it with pretty decent margins since AMD's card launched first, and there's still no solid ETA on when the high end version of kepler will be released, otherwise Nvidia would get roasted in reviews if it's only marginally faster too, but one has to wonder though what are the main priorities for the design on both tahiti and kepler.


Even though we use them primarily as gaming cards, i couldn't help but notice that the biggest performance increase with AMD's tahiti is in GP-GPU, as double precision floating point math got doubled over Cayman and is now twice as high as Fermi, as well as having direct hooks to help with programing likely using OpenCL.


So as much as we want maximum game performance, Nvidia also has to seriously buff up the raw math abilities and acheivable real world performance in GP-GPU, wich has nothing to do with gaming, yet the resources to do that heavy math are shared within the same die as the resources needed to make it a fast gaming card, so it's a delicate balance to make....As much as we're gamers above all else, it isn't just about gaming anymore, it's beyond that too.
