If you're only looking at new parts, then stay away from AMD. That is of course if you're only thinking about the quad-core processors, because Intel's QCs beat the AMD QCs in benchmarks. The AMD processors of last year stand up to Intel's quite nicely, but the newer processors are swinging in favor of Intel at the moment. As far as SLI or CrossFire, I am an nVidia fan. The first video card I ever bought was an ATI card, and I returned it, and got a 6600GT which served me well for 2 whole years on a P4 2.8GHz, playing most modern games at playable FPS (50+), and older games like Counter-Strike 1.6 at a constant 100 FPS. I just upgraded to a 7900GS because it was on sale, and I'm more than happy with my purchase. Now, the ATI models in the same range may be just as good, I'm not 100% sure as I didn't check out all of them, but I'd recommend googling some benchmark comparisons of the nVidia and ATI cards and see the results. Never buy something because the price looks nice, or the descriptions of the products, because [bleep], either ATI or nVidia could sell 3 or 4 year old cards and will still make it look like the best thing on the market with the way they word it on the box. Trust the benchmarks.
