Working on those links, but essentially it's one of the following:
1. MBP 15.4" with i7 2.66GHz and 330M 512mb GDDR4 (not best obviously for WoW, but as long as it can run it on at least medium settings, I really do love these systems for all the other reasons) - $2070 (on discount from work)
Obviously this is a "splurge" for the hw you get compared to others, but I really like the macs so long as they can run WoW.
2. Sager NP8170 15.6" with i72820QM 2.3GHz and 540M 1GB VRAM GDDR3 - $1480
3. HP Envy 14-1100 14.5" with i5 460M 2.53GHz and ATI 5650 1GB VRAM GDDR3 - $1300
4. Dell XPS 15 15.6" with i7 840QM 1.86GHz and 435M 2GB VRAM - $1600
