First build, need help! thank you

Hi!

I want to start to thanks everyone who are helping others, really. English is not my main language (French, Quebec, Canada), so sorry for bad spelling and synthax errors.

I currently have an athlon 64 3200+ that is getting old so I would like to use a new computer for gaming and working (mostly programming/web design).

I have a budget of +- 1,500$ CAN, I do a little video/pictures editing. I already have a screen and dvd drive. I am a speed freak, I don't do benchmarks but I want a computer that load things fast (I will use win seven 64 bit).

Well, I made a quick list of parts i'd want to buy.

Note : Ncix products only please, that are IN stock, thanks!. I have little experience in building computers, but I probably don't know all of the cooling, psu, etc rules.

Now all of that go for $1,340.39 CAN for the hardware, no taxes or shipping.

Do i need anything else??
Thank you for paying attention and helping, I really appreciate everyone's effort!

NCIX does price match so shop around with direct canada and newegg.ca.

You can save a bunch and get a better rebate by going with the XFX 4870, what resolution are you running on? You may be able to get away with less.

The OCZ platinum ram is significantly cheaper and will run faster
http://www.ncix.com/products/?sku= [...] Technology

the dominators are just plain over priced, havent figured out why yet, the difference between CL9 and CL7 on 1600MHz ram is more of a performance difference than 1066MHz to 1600MHz. Yes timings do make a big difference, and if you can get better for cheaper why wouldnt you? XFX provides a lifetime warranty for the card, and for the person you sell the card to. The chips are all made in the same fab by ATI and there isnt much of a difference even between the powercolor cards and the more expensive ones so im not sure who told you that XFX was bad.

Those would work, didnt realize the platinums were out of stock. put something between the ] and [ tags and then the links will work.
