I use 8800 GTS and it runs smooth with 16x AA and all high
Check with freaks list of Graphics cards but aslong as u have the HDD space, ram and processor, i cant see it being too much of an issue, the game looks better than wow's low graphics on low graphics IMO
Whats dissapointing about Scenarios?? Ill throttle the guy...
3rd question already answered
I would say this to u in reguards to quitting wow:
Buy the box, try the 30 days, get 1 char to atleast end of tier 2 (~21, u get mount at 20 ) so u can play a keep attack/defense, thats the beauty of this game, open world RvR
On the Ocianic servers i get the occasional one that goes for hours, the two sides of 24+ fighting over 2 objectives and a keep!
Have fun
i quit wow for war and came back the next month the box comes with a one month free subscription but it doesnt activate untill you put time on ur account by buying it so.... it's a pain in the ass for somthing you prolly wont stay with.
