Under my Windows 7 performance information it is listed that I have 2.5 Gigs of usable RAM even though I have 4 installed. I think this is because I have 1.5 GB of graphics memory but I don't fully understand what that is. I also don't understand the difference between the listed "dedicated graphics memory(512MB)" and the "shared system memory" that I guess make up the 1.5 GB I'm "missing".
I was thinking of installing a 64 bit version of my OS to take full advantage of my installed memory and I think my system is fully capable. I just need to have the right processor and enough memory to make it worth it correct? I assume my motherboard is capable if it is using a capable processor... Is there anything I'm missing?
