With default cooling, someone over-clocked their Core 2 Duo E6300 to outperform the FX62, so at the moment Intel is dominating the market (Even the stock E6300 for $299NZD is outperforming the 5000+ which is $539). But yeah, SLI is when you link two PCIE cards to make them run at the same time, one rendering the top half of your screen and the other rendering the bottom half (in theory). It is possible to SLI both Nvidia and ATI cards.

To add onto it though
Between the CPUs that the other person asked it is basically an older CPU that isn't the core 2, so for THAT what was said was correct really. Between those two, AMD does win. Overall, for more CPUs outpreforming the competitor, again AMD wins... but in the current gen of CPUs (if you can call it a gen) Intel wins HANDS DOWN with the Core 2 Duo in both price and preformance. I can't wait for AMD to get their hands on the fab process that was used to make the core 2 duo, AMD is going to come back with avengence I bet when they get that.
Also, the ATI "SLI" is actually called crossfire, and is a bit more advanced then the half and half rendering you were talking about. You can set one video card to any number of tasks like just be a physics renderer... think of that physixs card that was supposed to take the strain off your graphics card by rendering all the mini particle effects and such, and make that into a 512 meg powerhouse like a x1900xtx or something high. I'm not sure if the same holds true for the SLI though...
OP, to add onto what was said already about comparing the cards...
Don't be too fooled by the fact that most newer nVidia cards have more pipelines, they are generally a bit slower (when comparing an equal price) then ATIs. They make up for it in other ways though. In general, what I personally look for when choosing between cards (after price) is:
GPU Clock Speed
Memory Clock Speed
Memory Bus
Pipes
in THAT order. If there are different memory sizes available (like say 256 and 512) then I decide if the extra $$$$ is worth spending it. It generally is imo, especially for gaming in general. If you're just mainly going to play WoW though I wouldn't really suggest upping to the higher memory if you already have a (semi) beefy system behind it.
