WoW 5-boxing - hardware query
My PC is:
i7-920 running at 4GHz
6GB RAM
Win7-64 on SSD
WoW on Western Digital HDD
BFG GTX285 OC+ (1024MB) running the 257-21 drivers
2 x 24" 1920x1200 monitors
I grabbed an ISBoxer licence a month ago and have been easing myself back into WoW with some 2-boxing, which worked fine.
Today, I've made the move back to 5-boxing and have fired up my Shammies but am having problems.
For the past month I've been 1 and 2 boxing with the graphics set to the "high" setting on the slider and (both) clients at 1920x1200 with no problems.
When I try 5-boxing with those settings, I can't even load a 5th client before the system starts to struggle and I appear to be out of RAM.
With graphics down to Low (but view distance notched up a bit) I can load 5 clients and play, with some 500-800MB of RAM free.
The CPU is barely ticking over and the GPU, whilst busy, isn't quite maxed out... so am I really looking at more system RAM to fix this problem or am I missing some other issue?
What spec do other 5-boxers have and with what WoW settings?
