What I meant is would it be to laggy. Benchmark wise it is around 1800-2000 I did not know how laggy or well the game ran at that level.
For future reference, may be wise not to refer to graphics stutter of an underpowered system as 'laggy'. Lag is traditional and conventionally (at least by anyone that knows a minimum of computer terminology) a term used to describe the time it takes between the server and the client to send/receive information, and as such, could be misunderstood, thus hampering progress on getting your issue solved or any proper advice on the matter. For example, if you say to me: 'I am suffering extreme lag while playing games. What can I do to resolve this?' I would tell you to configure your router, upgrade your internet connection, etc..., when what you really needed was new computer hardware. Due to the lack of proper terminology, you are sent on a wild goose chase. Not trying to nitpick, just saying it could help you in the future to try and use proper terms when describing a problem. What you are referring to is graphics stutter or poor frame rate.
As for whether it would run decently on your system...well, there's only one sure fire method of finding out and now is the best time to do it, considering it's free. :)
