I don't recommend running a CMWW build with Archon gear. You have no APoC and your APS is on the low side so survivability will be an issue. You also have no LS and just 230 LoH so you'll die very easily, very fast, very often at higher MP.
I just logged out with a new ring and same build as yours. Now it's 290k vs 250k. The GC+pinpoint barrier were giving me a lot of dps. Most of the difference now is the higher Int I have, though I still have a bit more crit.
EDIT: I usually just log out with my normal buffs, MW, GC, Sparkflint, Armor, and scoundrel.
Well, that's my profile. I have about 300 more Int, 9.5% more crit, though slightly lower CD and IAS. It's not showing the extra ring I had one which was 122 int, 9% IAS, 29% CD and 4.5% crit. That plus pinpoint barrier is the 9.5% more crit. Without that ring my actual dps would be more like 280k which is a lot closer to yours.
I also use Glass Cannon for another 12% dps or so, which ends up being around 25-30k dps.
