Was going to set up a Poll,but was not sure how :??:  . Anyway,my discussion is about the new highend GPU`s,SLI and CF.Now i have 2 4870`s,1 GB each in CF,my natural screen res is 1920x1200 and i get massive screen tear.I have to have Vsync enabled in every game.Now i am led to beleive that this is due to the fact that the GPU`s are sending frames to the monitor before the monitor is ready to display them.Now with the new GTX580 for me one of those cards would be more than enough,now i have read that some people have these cards and the Ati 5970 in SLI or tri SLI,or the CF equivalent.Now unless your running more than 3 screens do people really see any difference in games with one screen running a couple of these high end cards opposed to running one.The reason i ask is that these new cards completley blow mine out of the water and i get massive screen tear with the ones i have got,so is there a monitor out there that can cope with lets say 3 580`s in tri sli or 2 5970 in CF without getting screen tear.I dont think that there is a CPU out there that could cope with the above configs without bottlenecking the cards,is not one of these cards enough?The GPU`s are getting way ahead of other pc components,so is one of these high end GPU`S more than enough?
Would be interesting to hear your thoughts on this.

The problem is that software is not developing in parallel with hardware; 9/10 games will not stress graphics cards to their full potential (mainly because these games are console-ported).

Now there is not a single processor alive that can feed a GTX580 tri-sli at 1280x1024, simply because it would generate too many frames. But at 2560x1600 and the triple-monitor resolutions (6140x2160 or something?), it becomes the GPU that is struggling.

Also, there is a very visible difference. Imagine gaming on this:


Yeah, jealous aren't you? I am too.

To answer your question, "Now unless your running more than 3 screens do people really see any difference in games with one screen running a couple of these high end cards opposed to running one", the answer is no. Monitors will usually only have a refresh rate of 60hz, or be be able to display 60fps. 30fps is considered the 'minimum' for smooth gameplay. So, can you notice the difference? 30->60fps, yes. 60fps+? No, not unless you're using a 120hz monitor (and even then, it's controversial how many 'fps' the human eye can see (stress vs nonstress, etc)).

Thanks for the reply,and yes i am insanely jealous lol,now that would be somthing else gaming on that. I dont think i will run two cards again,iam selling the two i have now and putting the money i get towards a single card. My monitor defults to 59Hz in most of my games for some reason,so there will be no need for a top of the range card.Thinking of getting a 6870,i think that will be more than enough.

The 6870 is a slight downgrade from your current setup (think of the HD5870 == 2(HD4870), HD6870 is roughly 10-20% under the HD5870).

If your setup was a crossfire setup (2 separate cards, as opposed to a 4870x2 card) then I could get two ASUS HD6850s and overclock them. A highly OC'd HD6850 will beat an HD6870, and two of them scale very well in crossfire.

Your current setup (2x4870's) is fine. Don't see any reason for an upgrade. Its still a powerful combo.

If you want the 6870, as Shadow said it might be a slight downgrade (oh so slightly), but if your going to sell the 2 cards you have atm then you probably not gonna spend a penny as the 6870 should come to roughly the same price.

If your in the market for the GTX580, then your gonna pay double than you would for the 6870. Where a 6870 CF setup would far outway a 580GTX in every aspect. As Shadow already mensioned, 2x6850's is a really good option. Read this.

If you insist on a single powerful GPU, there's no doubt. You cant go wrong with a 580GTX. But my moneyz!!!

Tbh,some of the new games that i have brought recently,F1 2010,Mafia II,Dirt 2 all seem to play better if i disable CF,i keep my PC all upto date with drivers and Bios and i definetly see improvment running the one card. If i was to get a GTX580 i think that i would need to upgrade my CPU and my MB tb,then it starts to get a little pricey.
November 13, 2010 3:04:22 PM

What PC u running? If its a quad core, don't worry about it. If not then yea, pricey :( 

The 6870 sounds to me like the most promising option then. At least after u sell your 2x4890's. You could always invest in a new CPU / Mobo with the moneyz you save on the 6870 - 2x4890's = more or less $0-00

I'd probably aim for an HD6950 when it is finally released. My guess for that card is $350 or so and performance somewhere between the GTX 480 and GTX 580 along with a large amount of overclocking headroom.

This is a really good option.

My specs are AMD Phenomn 9950 x4 BE@3Ghz,with my 2 1 gig 4870`s in CF,8 gig of OCZ ram @1066Mhz,24" monitor@ 1920x1200.
If your guess at $350 for a 6950 is about right then ill hang on,thats about the same price for a 6870 at the moment in the UK. $350 = about £216,which is around the price of the 6870.

Sorry,i have just been reading through this and i seem to have got away from the original discussion,sorry about that.

Performance wise they are basically tied, the GTX 470 leads a little in avg frames while minimum frames are higher by a pretty good margin on the 6870.

Price, the 6870 is $10 cheaper on Newegg.

Power Draw:

You have the 6870 being less than HALF of the GTX 470's power draw since that diagram is the whole system, and the graphics card doesn't take up a supermajority of the power draw unless you have CF/SLI.


You have the 6870 being a solid 15 C less.


The 6870 is quieter by a decent amount.

So:
Performance - Same
Price - 6870
Temp - 6870
Power Draw - 6870
Noise - 6870

Features wise they both are loaded.

Yeah, that guess was for the US price so adjust accordingly. For reference the HD6870 is about $250 here.

Yeah,that works out about right,depending upon the make,the price varies somewhat.This is the site i use over here in the UK http://www.overclockers.co.uk/productlist.php?groupid=7...
On here i read alot about Newegg,but i am not sure if we can buy from there.If we can we would have to pay the import tax so it would not work out much cheaper.
Looking at the graphs above,for the price of the 6870 its not a bad buy for performance.I have read that the 68xx series have second gen DX11,does anyone know if this has had any improvment. My bro has a 5870 and DX11 hammers the performance of the card.

Newegg has a US, Canadian and Chinese site I believe. Outside of those though you are out of luck.
Yeah the HD6000 cards have improved DX11 performance.
