NVidia 8600GT and ATI 4850 in same system possible?

Hey everyone,

I wasn't really in the market for a graphics card until I saw how ridiculously good the reviews and benchmarks for the new ATI cards have been. I currently have a 8600GT that drives a 24 inch dell and a 17inch dell. I have a Gigabyte P35-DS3P motherboard that has 2 16x pcie slots, one at 16x and one at 4x (correct me if i'm wrong about this). Would I be able to add a ATI 4850 (or 4870, or any ATI card for that matter) to the system and keep my 8600GT card in the system too?

What I am think is...
Using the new card (say a 4850) in the full 16x slot to run the two computer displays mentioned above (so 1920x1200 res, and 1280x1024 res) by DVI, and then have my old 8600GT in the 4x electrical 16x pcie slot to run my 30 inch Dell TV (at 1366x768 res) and maybe another monitor in the future (something small to use for spreadsheets and word).

I run Windows XP pro sp3, Q6600 (stock 2.4), 2gb (800) ram, oodles of hard disk space, oh and a Corsair 520 watt power supply (which I think will be plenty to power everything [let me know if you disagree--after you answer my primary question though!]).

Can I ran both cards at the same time like this? Will the drivers conflict? Do they need to be both ATI or both NVidia cards? Will my motherboard run two graphics at once? Will my power supply power all this? etc, etc, etc.

Thanks for any comments or help!

-PS What a value these cards are becoming. PC Gaming is getting affordable again compared to consoles (closer, not quite the same though).

Uh, its actually quite possible and easy to setup. Just plug in both cards, and you can the displays mentioned.

My mistake, I thought he meant if it was possible for them to work together... Now if I'm not a complete idiot, I'm pretty sure that's not possible.
