Which card setup is best in this situation...

So I'm looking to build a new gaming PC. I want all games to be able to run on pretty high settings. My goal is to produce at least 120fps (at least try to in as many games as possible) so it can take advantage of my 22" 120hz Samsung monitor.
I've decided to go with the Intel core i7 920 and 6gb of DDR3 ram. As far as the video card goes I don't want to spend much more than 300. I did look at the charts on this site to compare FPS with different GPUs.

I was looking into the Geforce GTX 285 and liked what I saw for the price. My question to you is, for gaming on a 22" monitor, would I get better performance from two Sapphire Radeon HD 4870s Crossfire'd together or just sticking with the one GTX 285?

I am open to suggestions if anyone has a better setup for around the same price.

Thanks

You might want to turn down your expectations a little, 120 fps is very, very fast and only a very high end system will get close to that speed, even with AA disabled.

My advice is to get the fastest single card you can, a huge PSU, and add another card later.

Yeah thanks guys. It looks like the Radeon HD 4890 might be best for me. Also, when crossfiring two cards together, I understand they don't have to be the same model correct? However I heard something about them having to be in the same series... does that mean I could crossfire the HD 4890 with any other 4800 or what? Lastly, when two different cards are crossfire'd, I heard that your system only recognizes the weakest card or something??

Thanks, that helped me out a ton. I'll probably end up building the computer with the HD4890 in august. Hopefully by then, something new comes out and prices drop even further.
