Tom's Hardware seems to share the same opinion as the other articles I've read at Ars Technica, HardOCP, and AnandTech.

I'm just going to continue with x86 until more apps (and games) have been ported to x64.

Games:

MMORPG:

Horizons -- visually stunning, awesome ambient music. excellent (ie the best I've encountered in a game)crafting system and nice server - specific storyline aspects (plague, releasing new races etc) combat rather boring, as it only has 5 diff types of mobs. No zoning (other than teleports, which are not necessary, but timesaving.

Dark Age of Camelot -- an oldie but a goodie. With the latest expansion, the graphics have been OMG upgraded, an all new end game Champion level system, player controlled mounts, more housing, new races/classes and more robust economy. This game (out of all I've played) has the best high end content (if you include the ToA and DR expansions).

EQ - don't waste your time

EQII - gets real old, real quick. Not alot of high end content, and the debt system positively sucks. One good feature is the NPCs talk. That's pretty cool. But that's about it.

City of Heroes - Not fantasy. 5 different mobs to kill, but with the new City of Villans expansion, it MAY be a whole new ballgame. I doubt it tho. Nice if you like that genre. The fly power is cool, tho. And they do special events for the holidays, like last year they had a "trick or treat weekend" where you would knock on random doors in the City, and you would get an enhancement (like a buff) or a few special mobs (witches, zombies, ghosts) would pop out. Then there were regular pops of "pumpkinhead", a BIG high level mob that it would take 5 or 6 people to bring down. THAT was the funnest part of the game.

WoW - my hands down favorite. Robust questing system, easy to figure out, not so much easy to master, talent system, and Normal AND RP AND PvP servers, depending on your taste. Graphics are more "cartoony" than the others, but you overcome that pretty quickly. They have made it less laggy in the capital cities (a munch needed imporvement) and the best part: user created Add-Ons that are not only legal to use, but encouraged! It's a whole lot of "makes life easier". The new battlegrounds (Arathi) still have major problems (IE, can't get in them after 8 hours of being in queue), but the new patch is said to have corrected that. They are coming out with expansions and new content 1 or 2nd Quarter next year.

I was involuntarily sent from WoW to DAoC by my Husband and his best friend (Hawkwind, I've mentioned him before) last week, so I'll be on that (again) until they get bored and go back to WoW. The good news is that I have a bunch of money on a 47 (out of 50) toon there, and DAoC has a "free level" system, so I'm gonna take advantage of that! Champion levels here I come!

Now if only I didn't have to work......
