My nba 2k10 is still slow after upgrading

[akoposiaj]

why is it that my nba game (2k10) still lags / is still slow even if i have already upgraded my pc from sempron 2.0ghz to athlon II x4 2.8 ghz?

here are my specs
board is asus m2n68
graphics card is on board geforce 7050 pv/nvidia 630a
ram is 3gb
processor is athlon II x4 2.8 ghz

is this a computer issue or do i need to upgrade another part again?

Well, you forgot 1 thing: you still use the onboard graphic...
That's why you still suffer lags.

No matter what CPU do you have, if you still use the onboard then you're not good when it comes to gaming...
Get a dedicated card, even any low-end card would still overwhelming the onboard graphic...
