You're running tri-SLI yet in most games outside of the commonly cherry-picked ones tri-SLI is the same speed or even slower than regular SLI, and I?ll bet tri-SLI costs a hell of a lot more than a single 3870 X2.
There are some differences worth considering:
1. NVIDIA drivers allow the user to create or edit profiles, which minimizes the "no scaling" issue.
2. The single 3870's performance is
far below single 8800GTX performance due to it's shader resolve AA, VLIW shader arc inefficiency, and texture fill rate deficiency. Being "limited" to a single GTX is a better place to be.
3. When you have multiple cards, as opposed to 3870X2, you have flexibility of use and disposal. For example, a person with two GTXs could keep one to power his secondary rig when next gen comes out, and sell the other to defray costs. He/she could make that sale in advance of the release of next gen at higher sale price, while using the remaining card. A 3870X2 owner has an all or nothing situation.

Then there's the issue of driver support and we know nVidia is generally piss-poor in that department. If they can't even program one GPU correctly what chance do they have of correctly synchronizing three of them?
We don't "know NVIDIA has piss poor driver support" BFG. Since Vista has launched, I've used a FX-60/NF4/8800GTX SLi rig, a E6700/680i/8800GTX SLi rig/ a QX6700/780i/3 way SLi rig, and a E6850/680i/8800Ultra rig. On these computers I've used/am using Vista Home Premium, Vista 32 Ultimate, Vista 64 Ultimate, and Vista Enterprise.
That's a lot of hardware combinations and every version of Vista.
You know what my "driver issues" have been? Some problems with SLi and Crysis, and occasional stops in Unreal engine games.
You're too unforgiving IMO- you were ready to crucify them over the the patch in Serious Sam
1 not working, and that game is so old there aren't many copies left where the foil in the cd hasn't oxidized.
You can't expect PC gaming to be like console gaming, and I can link you to reviews that say NVIDIA's drivers are better than the competitions. (and have)
