WoW and 2 graphic cards

[Lash]

I 3box on the same computer with 2 video cards(ati 4870 1gb without crossfire). With Innerspace you can specify which GPU a wow profile will use. Make sure you have a lot of ram and a fast disk to run 5 copies on 1 box.

For what it's worth here, I run 5 accounts with one machine (Dell 730). I have dual ATI Radeon HD cards (forget the exact model right now, I think 3850s), but opted to not use the Crossfire option, as I'm more a "divide and conquer" mentality. Each card supports a single 24" widescreen panel running at 1920x1200. I haven't run into any issues with supporting all this, even in Dalaran where I hardly even notice any lag, running with mostly low settings. I also don't have to worry about GPU affinities, since I balance the load at a basic level.

I would mention that clearing up most of the issues regarding "lag" (read: video sputtering and loading delays) in Dalaran had far more to do with getting excessive RAM, and required no tweaking of the video cards or settings for me. I run with 8GB of RAM now for these 5 accounts, and in Dalaran I tend to only have about 1GB to spare, at most, to give you an idea. This leaves me plenty of room to be running iTunes, IE, Firefox, Vent, and other applications in the background without slowing me down any further.

Do dual cards work for multiple monitors? Yes, though you should try to balance the load for best performance.

How well does SLI/Crossfire work with WoW? Seemed okay when I tried Crossfire at first, but I was only boxing 3 at that time, and I never had to deal with SLI with this machine.

Watch your CPU utilization and RAM usage, and disk access if you know how, to determine what is slowing you down the most. It's not always just a video issue.

EDIT: Oh yeah, using Windows Vista 64bit here, by the way.

Looks like MS fixed this problem a while ago. Can't say I've tested it (I only have 1 GPU currently).

Processor: Intel Core 2 Quad Q9550
RAM: 8Go
GPU: Geforce GTX 260
HDD: 5 WoW runs on a RAID 5 of 4 HD with 16Mb cache and 7200 RPM
Monitors: 22" 1680x1050, 20" 1280x1024; Main on 22", Slaves on 20"
O/S: Seven 64Bits
WOW Effects: Low
WOW Resolution: 1680x1050 for all but Toons is resize to 320x256. I switch between WOW windows several times.

I'm using Inner Space, G15 and G13.

I have 60 FPS on Main and 30 FPS on Slaves mostly of the time, with low effects. The FPS drop to ~25 on few zones and 10 FPS on Dalaran. My CPU and RAM is used at 100% and ~60% mostly of the time.

My goal is to have 60 FPS/30 FPS with effects to medium or high. It's not possible for the moment. If I just increase a little the View distance, my FPS drop to 30 on Main.

And my future goal is to have 5 monitors with 1680x1050 resolution.

I'm running:

Q6600 at 3.02 ghz (have not overclocked)
8gb 800mhz ddr2 ram.
1x 4870x2 video
10k rpm, Raptor HD.
Vista 64-bit, home premium.

With four clients running, I do not lose follow in Dalaran even with Crusader aura on.
I wouldn't say four clients is smooth in Dalaran or Wintergrasp.

With five clients, which is what I primarily box, follow sucks even dismounted at prime time.
At 3am server, five clients is fine on foot.

Everywhere else, including AV's or Shattrath runs just fine.

My system is not as good as the one you have listed.
I was planning on upgrading next summer, but am tempted to upgrade sooner.
Doesn't have to be a top-top end system, but I'd like to run smooth in Dalaran with 5 clients.

Sounds like a good rig, where is the bottleneck? Maybe 2 mid-range cards instead of one that can't use all its power? Or will it take an i7 system?
