Updated, Gaming Build, Need Help

APPROXIMATE PURCHASE DATE: Near future, possibly in the next week or two. BUDGET RANGE: Approximately $1500-1600 CAD, it's not set in stone though.

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Mainly for gaming, movies, digital art.

PARTS NOT REQUIRED: Mouse, keyboard, monitor, and speakers are not included in my budget, however I have a separate "budget" for these things and I'm open to suggestions on keyboards and monitors. I already have a G5 and nice 5.1 speakers.

PREFERRED WEBSITE(S) FOR PARTS: Trusted Canadian sites, I've only been searching newegg.ca so far though.
PARTS PREFERENCES: No brand preferences.

OVERCLOCKING: This is a possibility, assuming it's not that hard to learn. SLI OR CROSSFIRE: Again, a possiblity, I'd like to do whatever is best.

MONITOR RESOLUTION: 1920x1080 or 1920x1200

I'm still not sure what I want/need. This is just one that I found, but is there a better option around (or under) the same price?

Monitors - I pulled these two from recommended lists, but I'm wondering how noticeable the difference in gaming quality there would be between these two. Anything better at a similar price point?

This is going to be my first build ever, and I'd like it to last a couple years before I have to look into upgrading. I play MMOs, mainly WoW, I'll be playing the Cataclysm expansion when it hits, but I also like to try out new MMOs as they're released, as well as some single player games. Right now I just want to focus on a build that will carry me through the next two years at least at max settings.

My list of components are pretty much all from recommended lists, and I'm not even sure if I'm doing it right. If there are conflicts, or better alternatives, I would greatly appreciate the help.

As for waiting for the new cards... To be honest I'm a bit impatient, and afraid that it will just push the top end of my budget up. I'm not sure that it is necessary for my needs right now, but if I wanted to in the future, would I be able to upgrade, or would I have to start looking at a new build then?

i would say wait 2 weeks or so with 1500 CDN (about 1350 USD) you could be able to get the 5870 when it comes out

Well, what games do you intend to play? It will determine whether it's worth waiting or not.

yeah guy i have for you gpu and everything for gaming

look at this
