edit:lol missread it all.
as the other pointed out i think the setup is a tad bit weak, you should have invested some more money in it :/

I actually have the max foreground set at 100fps, and vert. sync on because I care about my hardware and computer. :P And I don't care to see 140 fps. O_o
It is sitting at 30fps constantly because I have Fraps set to lock the framerate at 30fps, for video file size and shit. I did some recordings at 60 fps a few months back, holy shit, like one boss fight was 200GB or so. Not even 1920x1080! So I was like, wow fuck that.
AND youtube doesn't even actually show past 30fps, so it would be a moot thing to do. :P
So is this "choppyness" actually fps lag or not..? What's your fps when you experience it? I had a problem with an old computer sometimes when the game would feel somewhat choppy but still maintain above 30-40 fps. I think there's an option to "reduce imput lag" or maybe the other one next to it, can't remember which, that might help. In my case it weirdly fixed itself if I'm not mistaken :] Weird shit is weird.
I have the exact same CPU, same OS (I assume yours is 64-bit as well,) same amount of RAM. Your graphics card needs to go honestly.
Also you might want to look at core unlocking your CPU, I was able to switch mine from the Phenom II x2 550 BE to a Phenom II x4 B50. See here it claims you can OC to 4ghz, though the highest I've had it go without BSOD is 3.7.
I went from an 8800GT card to a GTX470 and my frames went from mid 30s on avg to 60+ (vsync on, otherwise they jump to ludacris levels)
