Im actually running XP pro 64bit with 8 gigs ram..im not having ram issues at all, my system keeps up pretty decently, never see my core's being hammered by anything, I can easily 10box off my machine..though I didnt really pay attention as to what the framerates where..I did have to turn the alts video settings off of max to low to get that smooth, and i was only testing 10 inside Sm cath at the time..normally I only 5box.

well SLI isn't an option on dual monitors, despite nvidia's promises...just like the 3way sli off 8800's GT's they promised, only to quickly print a retraction statement. Unless they have changed this for the 260/280 models..I haven't really looked at SLI since. Its all about stacking 3 video cards into your computer to run 6head anyways isnt it? thats what i've done with my 3 8800's, although keep in mind you have to fiddle around with the nvidea control panel a bunch when u reconnect or disconnect monitors and move applications around..or at least i find I have to.

My setup: Dell XPS 730, 8 GB RAM, 2 x ATI Radeon HD3850 video cards, 2 x Dell 24" widescreens (2407 and 2408 models).

First question is whether you are using Vista 64bit that has (or can make use of) more than 4 GB of RAM? Otherwise, you need to keep in mind that adding more video cards will make your usable RAM plummet. Vista 64bit keeps RAM and video memory completely separate, unlike other versions.

Also, Crossfire/SLI won't necessarily help when using more than one monitor. In my case, I use one monitor per video card and keep Crossfire disabled. There are arguments for and against using Crossfire, but opted to go with dedicated video for each monitor out of preference. You can try with and without Crossfire and see how well they perform with 4 monitors. Is a simple matter of removing the Crossfire cable from the cards and disabling the feature in the control center software if you don't like it.

Edit: In case it wasn't clear, "More =/= better, in all cases" is supposed to mean "More is not equal to better, in all cases".
