I apologize in advance for being so uninformed

I am considering using an Intel i7 920 at stock speeds to run dual 5870s.

Will there be a significant bottleneck with the CPU, and if so, should I go with a single 5870?

You will be fine with it,i7 920 @ stock is plenty fast :)

afaik you will need to OC i7 to a decent speed(let's say @3,6 Ghz) in order to get the best out of your cards

Well that's needed if the OP plays @ high resolutions also in games which benefit from a higher clocked CPU like RTS games etc,most FPS games are GPU limited and it will be fine with a stock 920

First off, Thanks for the quick replies!

That's what I figured. I also want to be able to go a while before having to upgrade my video hardware, and may overclock a tiny bit on the CPU down the line, as needed.

So, I should be fine with stock speeds if I were to play games at, or just above 1080p, with max settings?

Yes u will be fine,however as i said some RTS games like World in conflict etc benefit from a higher clocked CPU.
As an example i have a Q6600(which runs @ 2.4 default) and i OC'd it to 3.4,in games like Crysis,Bioshock and some other FPS shooters the difference wasn't noticeable but in games like World in conflict i get a good boost in FPS
