what kind of speed increase would i get over my current 300gb diamondmax10 with a 74gb raptor in HL2 (loading times and stuff affected by HD) and games in general (since it would be my gaming HD mostly)? i was looking at getting one since they say a true beast rig has at least one of these... but they're pretty expensive at the gb, especially in canada. it's basically the same price as my 300gb. who thinks it's worth it, who doesn't?
