I am building a new computer, my first and i have some questions about memory. All you gamers will be disapointed but for my situation i got a Intel P4 3.0 and a Asus P4P800 SE Motherboard. I also got a WD 80GB hard drive. I am stealing a Video Card from my parents computer do to lack of funds it is a 128 DDR ATI Radeon 9700 TX. I am wondering what i should do for memory I will game but computer is for large engineering programs. So what kind and how much memory do you recomend. Or even help about build first computer is good.
