So..after reading about this, I have a few questions. I just had to make an account to ask my questions!

So if the CPU is storing the value in its register and telling the memory to access it, why is it that we need a 64bit operating system to utilize the ram? What makes the 64 OS necessary? Aren't the processes just being handled by the CPU and memory?

Also regarding the video card portion, which is slightly vague to me..if I had a 4gb video card, would that mean that I'll be losing more than I have of system ram? Would that make my computer inoperable?

Thank you for answering. I'm sure the rest of the community would like to hear about this too!
