But your going to need a huge power supply and the fastest processor out there and then OC it to get 100% capability out of it.

I really hope your not serious.
Two 4870's compared to 1 4870 are either the exact same performance, 1-2 fps lower, or much higher in most benchmarks the performance does not "decrease" like you make it seem. Therefore a 4850 would infact NOT out perform a 4870 crossfire rig, or even a single one.
And as for your theory about SLI, you are TERRIBLY wrong, when you SLI 2 cards, you(ON MOST BENCHMARKS) Almost increase your performance by 1.5 times the original performance if not more.
Oh and by the way SLI is for nVidia cards, and Crossfire is for ATi cards.
Oh and yes, 1 more thing, you do not need a "huge" power supply, all you would need on an SLI rig is about a SOLID REPUTABLE 650 Watt PSU with enough amps on 1 rail to support two cards. If you want to SLI/Crossfire high end cards, I'd recommend a good 800 watt.
Corsair makes great PSU's.
