Gameplay should be your main concern, not graphics. Becides, RTS games don't rely as much on GPU. They're more CPU intensive, which is why dual-cores are good for all the latest RTS games.
That's because World of Warcraft brought in money. Blizzard earned millions in just WoW subscriptions alone. It definately does suck though...Starcraft Ghost was looking rather interesting. Until they put it on indefinite suspension.
Agreed. Call of Duty 4: Modern Warfare is looking rather sick. I definately can't wait. Bringing the franchise out of the over milked WWII timeline is refreshing.
