Hey everyone. I'm new here. Quick question. My Dell XPS 420 came with 3 gb of memory. I have upgraded the power supply to a 650 watt unit and am upgrading the graphics card to a Geforce GTX660 tomorrow. My question is, do I need to bump the memory to 4? I don't believe I can go above that as I have a 32 bit OS of windows 8. Preciate the help.
Yes, you can upgrade to 4GB. Well, your system supports a maximum memory of 8GB regardless of the OS limitation. If you need more than 4GB of memory all you need to do is run (install) a 64Bit of Current OS (windows 8). If you are using the system for basic stuffs and nothing memory intensive then anything between 2GB-4GB should be fine else if you are into CAD or video rendering or gaming etc then 8GB should be pretty good.
