Looking for advice on the best solution for dual display gaming/other. My board supports SLi x16 and I've currently got dual 8800 GTSs running in regular (non-SLi) mode and while I can get 60 fps running WoW in FS with one monitor enabled, as soon as I turn on windowed mode and fire up the second screen, I fall to 15-20fps and if I actually run anything like an HD .avi with VLC, I'm lucky to keep 10fps (and will occasionally hard lock).
Is there a sub $500 solution that will keep my framerates acceptable and not crash? Or am I asking too much?
System is currently running Win7 RC 64 bit w/4gb ram (although performance was similar with Vista 32 bit utilizing as much of the 4gb as it would see).
If you're not running them in SLI, a good single card would probably work best for you. While the 8800GTS isn't exactly a current card, its no slouch either. I'm wondering if its something in your configuration. Sounds like you have some sort of a bottleneck somewhere. You should be able to run 2 instances of WoW. Its not a very graphics demanding game. I certainly don't think you need to drop $500 till you really know what the problem is.
Try removing one of the cards. Assuming the 8800GTS has connections for 2 monitors. Otherwise, try running 2 instances on one card on a single monitor. You might also try the WoW forums.
