New ~$1,000 PC for Planetside 2

[Retrograde]

Thanks in advance. This is a great forum. I'm pretty pumped about ps2. So.....

I need to get a new pc for planet side 2. I'm using an older mac so I'm out of the loop on pc tech.

I'd like to spend about $1,000 on just the rig. I have a monitor and all the peripherals.

So here are my questions:

What's better in general for video cards sli or single card?

Higby indicated that nvidia might be better for physx. Is nvidia better overall?

If you had to buy a 1k rig what would your priorities be

Is there any reason to increase or decrease the budget a little? (more bang for a few bucks more?)
