Well, then I say upto ~1.2k players along with any website system. A little depending on scripts (they can go rough and run out of memory, or like on Eternia, use up a large potion of the CPU). You'll need to use 64bit to use 4GB in total (4GB - ALL other memory, like CPU cache, disk cache, graphicard memory etc is max on 32bit).
I use a 32bit system atm, i'm considering upgrading.
So to my understanding, you're saying that I wont need a hardware update for quite some time?
That's great, thank you Stian
Rep for you
