i suggest one harddrive per wow session, helps alot on load times, i know it did for me on just 3 of them.

my setup is[*]C2D Q6600 @ 3000mhz (333*9) [*]1GB*4 = ocz (800mhz 1:1 @ 4-4-4-15)[*]8800GTS 640MB BFG OC[*]2xseagate 250GB 16MB raid 0 (just my os) [*]4x250GB WD 16MB for (wow )[*]2x Benq 24" @1920x1200 (dualview)

i could run 4 wows fine at 1920x1200 (playable above 40-80frames each session depending on where i am.)

the gtx should help alot.
