$700+ Gaming PC, need advice

This is my first build, i did a lot of research on each part and how to choose them , but i need some advice and opinion.
I'm building it to play games of course, and i want it to last *forever*, I probably won't plan on making a second build but i will upgrade when the parts are cheaper. Hopefully i can buy it this year, otherwise it'll be early 2010.

So right now approximate cost is going to be nearly $800 (excluding mouse and monitor, already chosen and I already have some speakers and a keyboard).

So, what do you people think? Is this build plausible? Is there anything i can do without and replace for something cheaper?

BTW, does the hard drive matter much? I don't plan on filling it anyways. And is it possible to use any optical drive, i have one laying around somewhere...

Also, just a random question, but what is the purpose of a DPI adjusting button on the mouse? I don't get it.

Sorry for all the questions! Thanks everyone.

Looks like a freak of nature config - ddr3 with AM3/I5/I7 not dead end LGA 775 platform @@ Counter proposal:

Hmm... I don't know where you found those items but i don't think i can do it because the ones i found are more expensive.
BTW i have to use newegg.CA

Try this one on for size - prices and links are to Egg USA also as I was off working on it before you listed CA preference. Oh how I wish people would follow the model for listing data and then we would not have this problem.

4 GB is definitely plenty for now - and you can always add later - in a year or two, if you have to - as long as you have open RAM slots.

Here's is my final decision (maybe), bold in what i changed

Is this build any good? Any changes to be made? No counter offer right now, Ill be back tomorrow!

???
For only $25 more you can move from the puny quad core 925 at 2.8GHz to the cuad core 955 Black Edition (unlocked) at 3.2 GHz. That seems like a no brainer to me.
[Edit - corrected to show 925 is quad core - thanks batuchka]

And the 500w PSU I listed is a better PSU and cost $30 less AR - there is the money to pay for the faster PSU

And here is a much better HD - same price, faster, 500 GB compared to 320 GB and 16MB cache compared to only 8MB on the WE.
