Well, the thing about is that like I said, I multitask a fair bit. Just today I saw something thats going to influence my decision.
I was usinga crummy computer at work with only 1GB of RAM. I had as many apps as I could shut down, I tried to strip the system to bare minimum, and illustrator was still giving me problems with memory because I was working on something 4x12 feet.
In BG apps alone I can probably use up 512MB and up, with Windows Media, various IE, Avast, Spyware Doctor, Messenger.
While it is true that 4GBs will probably do wonders, and probably be sufficient for know, it might come in handy later on, but I think youre right, I would be better off getting some fast DDR2-800 RAM and overclocking the CPU. I think ill see much better results if I can get the C2D around 3.0, than adding an extra 4GBs, and it will be a heck of a lot cheaper. Plus ill probably keep the FSB around 1:1 ratio. I think thats the way to go to get a kick ass system.
