you have the integrated intel extreme graphics chipset which I believe is non-T&L but you also have the 2.8GHz processor which will take care of T&L. your computer is above the minimum requirements to run the game, so yes, it will be compatible.

however, if you are not satisfied with the graphics performance of the sims 2, check to see if you have an available AGP slot on your motherboard. if you do, you can buy a separate graphics card with dedicated memory and that will definitely improve graphics performance, but again, it depends on how your computer handles it and how you rate the importance on graphics performance

edit: managerjosh, i think DDR400 memory will only work with motherboards that have a FSB speed of 800MHz or higher. the one she has is 533MHz and the fastest memory that will support is DDR333. correct me if i'm wrong

also, abby: if you're getting the special DVD edition, make sure you have a dvd-rom or dvd+/-RW drive (can also be a dvd-rom/cd-rw or dvd+/-rw/cd-rw combo drive). if you ordered the CD version, you don't have to worry about this
