FSX on 720p

I want to build or order a new gaming computer.

I want to connect my PC via HDMI to my 50in 720p plasma (1024*768) and to my 22in comp screen (1680x1050)
I want to play Microsoft Flight Simulator X, maybe not at the highest settings but I want it hot, it would be the only game I'll play
My budget is 700-900 $CDN
I want to play mkvs and other HD content
I want to set it up this week or next one.


Here is where I'm heading, please suggest or comment, prices come from NCIX and Newegg Canada:

I will put my own HDD 320 GB WD SATA and LG DVD burner SATA and my new version of Win7 64 Bit pro.
I want to wait a little bit in order to get solid state drives in the future.

What do you think? it would be my first built, or I'll ask somebody to build. Are there any overkills, underacheivers?

I want to go for Radeon GPU cause I like the HDMI THX sound compatibility via HDMI, but am not blind to Nvidia yet.

Just make sure the RAM you chose is on the motherboard's QVL, to make sure it's totally compatible. Other than that, I don't have complaints about your system, except that if you're building a system to "just" play FSX, you can get away with cheaper parts—that are on dead-end platforms (socket LGA 775, etc.)
