is it possible to run sims 3 with no lag at all?

is this game poorly done or is it my rig isn't good enough? i get alot of choppiness with all settings maxed out, if i lower the settings to med, its better but not prefect. Sims 3 + all expansions

i7 920

intel mobo

6GB Kingston HyperX

EVGA GTX 460 OC'd GPU Clock 820Mhz Memory Clock 2000Mhz

WD Black HDD

Your system should easily run it.

Turn down the settings to some of them on medium might help a tad...

My wife plays Sims exclusively, I built her PC to play anything out there maxed out and it STILL runs like $%^&. It is just crappy coding.

Some games dont work good with OC gpus.

If it helps, I'm running a i7 930, 8gb g.skill, 5870 Vapor-X, on an Intel SSD, and when I play Sims 3 it can be a bit laggy at times as well with maxed settings. This is pretty much when I'm speeding up time 3x or 4x though. The picture can also be a tad choppy when panning the camera, which I don't experience in other games. It's not enough to make me never play it again, but it's annoying none the less.
