you can never have enough vram, as we all know games new more and more, it will come in use down the road. Could you imagine 2 of those in cf!!!!!thumb.gif

Honestly I don't get the complaints about VRAM. We already know you don't need it for your 1080p screen. Then again just because it's not for you don't mean there isn't someone out there it is for. I could easily see someone running tripple 1600p screens jumping on a card like this.

What about... 2560 x 3 x 1600 = ( 1.97 x 1920 x 3 x 1080 ) with 16x/16x + max everything else

Awesome card even without all the VRAM.

I guess we're going to find out the VRAM limit to three monitors in either Surround or Eyefinity and if there is any differnce between 4GB VRAM or 6GB VRAM soon enough. We all know there is a limit eventually just never had cards that could show us where more VRAM isn't going to make a difference. There's also some point where a card with a greater processing unit even with less VRAM will out perform a lesser GPU with more VRAM even on multiple monitors. Again just never had the cards to show us those ceilings.

Completely different story on single monitor. All that VRAM would be a complete waste of money except for the sheer GPU processing performance factor only. As we know from current games that 1.5GB is more than enough. Example shown by Linus from NCIX who showed 1FPS difference in 1.5GB vs 3.0GB card on single 1920x1200 resolution monitor. Or where the GTX 560ti 448 1.2GB can out perform a 6950 2GB card whether they're over clocked or not when on a single monitor.

Good times for those running multiples with variants of 4GB and 6GB coming down the pike for both sides of the fence. smile.gif

The 7970 doesn't have the texture and pixel fill-rate to saturate six gigabytes of video RAM at twelve megapixels to maintain any playable frame rate. Six gigabytes of video RAM is useless and is ultimately a marketing ploy.

You dont need triple 1600p for jumping on that (I would if I could afford it) a 5x1 1080p in portrait (10 megapixels) would already benefit from that.

Depends on what you consider playable framerate. I'm running 10 megapixels on 6770 with 1 Gb of vRAM and I'm able to get playable frame-rates with careful tweaking. I feel the limitiations of vRAM a lot more than I feel the lack of muscle in this card. If you give the card more work than it can handle the performance degrades gratefully, if you hit the vRAM limit the performance drops off the cliff. So having a bit extra at very high resolutions would be beneficial for smooth game-play in my opinion.

My "playable framerate", btw is relatively low. I can live with 30 fps average as long as the minimum does not drop under 20.

I will need to upgrade my gfx card sooner rather than later but atm these that are on market are either outside my budget or have connectors that are not suitable for my purposes (I need to run 5 displays minimum and only cards from the latest gen that can do it atm are Asus and MSI 7970's as displayport 1.2 hubs are not existing on market so the usual 2x mini DP on reference design is good for only 2 displays, not 6 as marketing claims). I would like to see 7850 or 7870 with 5 or 6 displayport and 4 Gb of vRAM TBH.

yeah but in the end when you start to Get games to use 6 that card is old (in PC gaming technology world) it seems making a 6gb version is more a market thing for them to sell more expensive cards

yup, most peeps say BF3 uses 1.5 2gb of vram, so we know that frostbite engine will be use for more game, so more vram will be needed in futer games. And I'm sure the 6gb will later a long time like the 5870 did. PLus its future proffing you rig for a while, be as well all know in the computing world future proff is a loose term. Be 6gb is alot, If I could aford one I would pick one up.

Aint BF3 a 32 bit game same as almost all of them out there currently ? If its 32 bit it cant use more than approx 3,5 gigs.
