Can my computer run Battlefield 3?

[Sidewalk]

FTR: I don't care much for graphics. I'm more interested in FPS.

3.0GHz AMD Athlon II X4 640 quad core
8GB DDR3
9800gt (I know, but my HD4870 broke...)
MSI 880GM-E41 AM3 AMD 880G HDMI Micro ATX AMD Motherboard
Windows 7 Ultimate x64

It's the only game I'll be buying in 2011, so it'd be great to know if my computer can run it or not before I drop $60 on it. Otherwise I'll be playing it on my stupid PS3.

On an unrelated note, can I change the button configuration to fit my liking without causing all kinds of issues? I'm more of an up/down/left/right guy instead of a W/A/S/Z, if you follow. Thanks in advance.

your video will probably barely meet the minimum requirements. This might help - YouGamers - System Requirements

It says it's fine which is about what I expected, but I'm curious as to how many FPS I'll get exactly (medium settings).

Yeah, it has to be fine. A 9800GT is better than what is in consoles which will be running this game.
