Well, yes and no. You need a good processor in the mix with your ram, or else you're not going to notice much of a difference.
This Laptop would be good for what you need, especially since it has the 4 GB of DDR3 ram, and yes the processor is a Pentium Dual Core, but it's not a bad processor. It'll be decent enough for what you need it for.
It can also play games if you wanted it to.
