Widescreen Gaming Forum

Hello people. Please forgive me if this has been discussed but I have used the searched function but only found limited return but not the answer I was looking for.

Basically I have one 30" Dell 3007 and I am looking to increase by buying two more 30" 3008s plus a ATI 5970. My question is does the 5970 Eyefinity support using 3 x 30" Dell monitors using its native resolution spread over 3 screens for games. Reason I am asking is my search has only returned people using 22" or 24".

Originally I was going to go 3 x 30" with triplehead2go but found out the max resolution support was 1920x1200 so i ditched that project.

Also is there anywhere on the forums which you talk about furniture i.e desk suitable for a 3 monitor setup.

Hope you all have a great christmas.

Check anandtech's review. They needed some sorta adapter thing to plug it in.

You may want to take note of the image in this Eyefinity report:

Yes, thats 6 Dell 3008's being powered by a single HD 5870 Eyefinity6 board.

The 5970 supported 2560x1600 on all the outputs, and as the 3008 has a native DisplayPort input you can run the 3007 on one DVI, one of the 3008's on the other DVI and the other 3008 on the DP.

Be carefull with this as at 3x30> your 1 gig framebuffer is going to get overrun. There are people on here that are having a heack of a time running 3x24 in monitors. I think 1680x1050 is the sweet spot for eyefinity. I think that the 5870 six port may run better than the 5970 because it has 2 gigs of ram. Most people are saying that the framebuffer or the amount of memory is the issue not the power of the card. I just got my 5970 last night but have not had time to set eyefinity yet. Will hopefully do that to night.

Thank you for your feedback.

Does the 2GB on the 5970 not help the buffer problem you are mentioning as the 5870 is only 1GB?

No it does not. The 5970 cannot combine the 1gb from each core. The most memory you have available is 1gb.

Just to give the reason behind this, SLI and Crossfire both require that each GPU have its own memory. So the 2GB on the 5970 is operationally equivalent to 1GB on a single GPU board..

So ultimately which setup do you recommend I should go for to obtain viewing eyefinity over 3 x 30" Dell monitors. This is something I will start after christmas as I want to improve my experiences in racing, flightsims and other games.

Currently I am running a XFX Nvidia 295 1796RAM card

Hi, I did exactly what you are planning to do recently. I had a PLP setup with a Dell 3007 and upgraded by adding two Dell 3008. I also switched from SoftTH to Eyefinity with the 5970. The new setup is impressive when everthing works, but it is still hit and miss for me. Games like Call of Duty: WaW, GRID and the Source titles run totally smooth at high settings, but I haven't had luck others like CoD4 or the Crysis games yet, which I got to run better with SoftTH and a GTX285. I must say it is still early days and I have a lot more experimenting to do.

The 1Gb framebuffer also worries me a bit. FarCry 2, for example, runs smooth as silk but occasionally freezes for a split second when I run or drive. Lowering the detail settings doesn't seem to help. This never happened with my GTX285 with 2Gb VRAM, although it is not as fast. For this reason I think that crossfiring a 5970 would be a suboptimal solution, and I'll wait for cards with more VRAM before I would upgrade again.

Overall I'm very happy with this setup and I certainly recommend it, as you can expect the drivers to improve.

I would think the 2GB frame buffer explains why Crysis ran better on your GTX 285 at that res, since I've heard the game is fairly tough on the graphics memory.

When you say PLP setup, I assume you're talking 4960X1600 with a 30 inch and two 20s? What did you have to do to get Crysis to run on that with a GTX 285?
Although I'm surprised a GTX 285 had enough power to run the game well on a PLP setup
