My iLevel findings

[Moloko333]

I took a level 29 blood elf disc priest and these are the stats for different ilevels

iLevel 33 int 194 crit 13.07% health 5520
iLevel 45 int 194 crit 13.07% health 5592
ilevel 49 int 194 crit 13.25% health 5592

So the difference between GS 33 and GS 49 is .18% crit and 72 health

Now to compare a level 29 blood elf warlock

ilevel 48 int 194 crit 11.66% health 6456

and a level 29 gnome warlock

ilevel 48 int 197 crit 10.66% health 6456

And finally to compare a level 20 gnome warlock

ilevel 44 int 179 crit 14.90% health 4750 dmg from haunt 1198

and an level 20 undead warlock

ilevel 45 int 172 crit 14.90% health 4769 dmg from haunt 1165

Making the difference between the two 29 health and .028% more damage from spells. Those differences are racial, not iLevel related
