If you are running on stock ICS, then make sure you've done a factory data reset after the update to ICS, and whenever your phone slows down, switch off your phone and switch it on again.
Also, I'd suggest upgrading your card to at least an 8 GB one, as that would help you install more games and other media as well. Also, ensure that you go for at least a class 4 card (though personally I prefer a class 10 card for its speed)
Also, note that not all games run on the stock ICS, for example "Riptide GP" usually crashes on this build and so does "GTA III", so to rectify that I had installed a custom ROM. If you are willing to do this to play games, then you can check out my rooting guide.. lol
