I currently have an ASUS M2A-VM motherboard. It has 3 GB memory currently. It is running on an AMD Athlon 64 X2 Dual Core Processor 4200+. The on board audio went out and so I ordered a cheap audio card. My question is, should I consider building a new computer or just upgrade the memory? All we do is internet, some graphics and home videos, and the kids are starting to play some games like the new Toy Story 3. Is the processor I have still pretty good or totally out of date? Any ideas or thoughts???????
