... and way more expensive. You have to pay for a second video card, as well as adding at least 50$ to the cost of the motherboard. You also have to use a buggy Nvidia motherboard if you want to use SLI. Then theres the power reqirements which translate to bigger electric bills. And the fact that two cards never, even on their best day, run more than 50% faster than a single card.
Heh heh, yeah, I guess the electric bill might go up, but realistically speaking, its not equivalent to anything substantial, like running an AC unit on 40 degrees for 10 hours.
As for the speed, I'm not sure if I misunderstood what you were trying to get across, but I can assure you that 2 videos cards run at a considerably faster speed than just one of the same type. I think what you might have meant was having 2 video cards doesn't mean twice the power, usually it means anywhere from 150% to 180% the power of the single card. Just like multiple CPUs you don't get 100% usage when you have multiple devices competing to do the same thing.
I"m not going to try to save Nvidia by saying the cliched "I've never had a problem with it." that most people say about whatever they're defending. If Nvidia boards do present an issue, you may be better off not using them, but weighing the common MB difficulties with the handy SLI feature can warrant using them anyway. Any type of motherboard will have its problems, just different ones.

If you have a dual core and at least 2gb of ram, Vista runs fine at this point. If Vista has at least that level of hardware, it runs programs just as fast as XP at this point.
Its not the speed of the OS I'm talking about. Vista is extremely unreliable, it was released premature, an annoying trend Microsoft enjoys, and still lacks oodles of compatibility with drivers and other things. Many games and programs you may enjoy wont even run on that OS unless they've been released fairly recently, and even then its a gamble. Plus, if you intend to do anything that requires creativity or thinking out of the box, like non-factory overclocking, or anything interesting, don't count on it working very well, if at all, with Vista.
I've been through tons of OS setups, from win 3.1 to Win XP64 (bad Idea) and I've even had to deal with Vista a bit (I'd never install that garbage on my own computer though.) Right now your best choice is to go with WinXP 32 bit, its stable, lots of support, lots of compatibility, and all the drivers you'll ever need.
