Well you should be able to run that with no lag ... But some people do not understand the issue of " lag".
Lag happens because of communication between your pc and the server. You hear alllll these people talk of broad/high speed internet. Well the issue is this.. They alllll speak of having this over powerful download. "i have 3.5 mb download", " oh yeah well i have a 5mb download" and so on and so forth. The issue is you don't hear anyone talking about their UPLOAD speed. upload is the most important thing in gaming ( aside from your system). It is awsome to have this great system and only end up with 90k-128k upload. lol.
