Good internet, weird lag.
Hello! My friend has the same internet as I do, same plan and what not, and a better computer than I do. But when he plays any game like Super Street Fighter IV or Black ops for Ps3, it lags, whereas mine doesn't. Any way to fix that?
You have a better computer, maybe from your description he is using WIFI (wireless) connecting the router to his device (PS3) so the lags might be the results of signal obstruction.
You have the same plan but are both of you using the same router model? If wireless try using 802.11N (N the fastest) wireless router.
