I have 8GB running Windows 7 64-bit and holy smokes, it is amazingly fast. People always say what the heck would I do with more than 4GB of memory? Well let me tell you, I multitask the crap out of my computer. I do many things and multitask all the time. It’s amazing how much 8GB gives you the freedom to do.
The motherboard I have allows up to 8GB only so if I wanted to go up I will have to upgrade to the Intel Core i7/X58 or P55 chipset. We’ll see which direction I go. I had really lost my interest for upgrading my computer but now that I see how quick things are compared to my old computer I’ve got that itch back.
