Need some opinions on new Home PC

Hi all Im a Canadian currently living in Quebec.

Now I'm planning to buy a new computer for home use. My mom surfs everyday and sometimes runs some heavy office applications. Myself will be surfing everyday as well and play non 3D games like Starcraft Friday afternoons, and usually play some intensive 3D games in weekends. I often download movie, music and watch & listen to them. Most importantly, I will play lots of games during holidays when I can.

The budget will be $900 CAD at most (monitor not included, all other necessary parts included), but it's the best to keep the money under $800 CAD.

Online shopping & shipping will be the best method for purchasing. If not, local stores in Montreal is also good.

Here is a list of parts I've found in Canadian online sellers (cheapest possible):

I just want some opinions on whether this system is good or not (cost effective), OR you have better parts. If any of the above sellers has high shipping costs/no shipping please tell me. Thanks.

For the PSU, I have been using my old computer for more than 3 years and the PSU is still good no problems! I bought the computer from a random store and the case w/PSU is not even branded. If I'me ever gonna spend 50-60 on a PSU, can u recommend a good one?

I went to asus.com and found specs for A8N-E, it says it supports SATA2.0 on the overview page, and then SATA 3GB/s on the specification page. I'm not sure whether they mean SATA II or SATA2.0.

I didn't choose X800GTO for a reason. My friend recommended it.

For the RAM, OCZ, Corsair, and Kingston are the best manufacturers IMO. I don't really know if other manufacturers' products are good or not.

If you don't oc much then no need for the big name brands. well, their value Ram is only a few bucks more expensive....

the x800gto is a beast OC'er, it only lacks support for new visual effects

I bought the ASpire CW-500WP4 for $30 (cheap) but it works great. however it is from newegg, which is in the US. I think the FSP has one for $50, link here.

See if you can find the same model in canada

Actually, I'll just go buy a PSU, I'm not risking my new pc. Also, is it good to cut down the price on the video card? I've never played games like Doom 3, NFS9, Quake3, AOE3, etc, because of my old integrated Intel Extreme Graphic card. Will X700Pro be enough for these games?

I got a great ASUS 6600 128mb for 140 at PC Canada. I think they have the GT for 210.

The 256mb isn't too much more than the 128mb versions.
