Im fairly new to pc gaming and kinda need some help. I have an Inspiron 520 64-bit system win an AMD Athlon II X4 630 processor 2.8 GHz and 6 GB of RAM. I was wondering what i should do to make it run faster. I usually play just call of duty 5 and team fortress 2 but it runs slow, and the fps is really low. Just wondering if I could get any suggestions on what to get. Thanks
