I have an Acer Aspire 5552 with 4 gigs of RAM and an AMD Athlon II P340 Dual-Core Processor 2.2 GHz. I was wondering if it is worth the money to upgrade my RAM from two 2 gigabyte sticks to two 4 gigabyte sticks. I don't know if the upgrade in RAM will make a difference that is large enough to feel or if I should just keep rolling with what I already have. Thanks everybody for your help.
For x64 bit OS, upgrading RAM is generally a good idea, but how much depends on the applications you run. I also recommend everyone that is interested in spending money on upgrades to first take a look at secondary storage (hard drive). This is the slowest component on your PC. If you have a slow HDD and replace it with a faster, better performing one, you will most likely see a better peformance increase than by just upgrading RAM.
