I recently plugged up my old desk-top from about 5 years or so back up. I have been wanting to get into PC gaming for a while and thought I should see just what it could do. I installed Doom 1993 and Quake onto my computer and have had fun playing them the last few days, but I would like to know if there is anyway to upgrade this to be able to run some better games or should I just start a complete new build. I don't know that much about PC gaming yet but here are the specs. I have already read that this is a very weak machine and I am fine building a new one.

Intel(R) G41 Express Chipset
Intel(R) Celeron(R) CPU 450 @ 2.20GHz
ACPI x64 based PC
2.00 GB Ram

So can I do anything to make this computer run some newer games (not expecting much) or should I just build a new PC? Thanks.
