Help! Building a new rig need some advice before buying :)

Hello guys and gals, as you can see I'm fairly new to this forum and would like to ask you fellow mates for some advice. I'm about to build a new rig in these few up coming weeks and just want some feed back on my build versus price range.

I went to a local store and asked for a quota on the following:
-Intel Core 2 Quad Q9300 2.5GHz 1333MHz FSB
-Asus P5N-D SLI ready mobo
-4GB DDR2 800MHz
-500G 7200rpm SATA2 HDD
-Internal Cardreader
-Antec Gaming Case 300 w/ 600W
-LG 20X DL DVD+/-RW
-Logitech Wireless Keyboard
-Logitech Wireless Optical Mouse

The owner quoted it about 914$ before tax. That's the best he could offer. So after tax that'd be around 1100ish. My ultimate goal is to tone it down to around $1000 near or below.

Note: I already have 2 x BFG Geforce 9800GTX+ OCX so it isn't added in the price.
Purpose of computer - mostly gaming.

If I wanted a smaller harddrive, the difference would be -20$
If I didn't want the internal cardreader, the difference would be -6$ lol
If I didn't want the keyboard / mouse combo, the difference is about -30$

My Questions:
1.) With you guys's experiences, is there any possibilities that I can find a better deal let's say...via Newegg/NCIX/Tigerdirect?
2.)Do i need a bigger PSU for the two cards? 600W a bare minimum for the 2 9800 GTX OC's?
3.) Any advice on decreasing or finding cheaper alternative for let's say...CPU, MOBO, CASE? ETC?
4.) Last but not lease...do i really NEED the Q9300? Biggest bottleneck at the moment. The CPU is probably the most expensive part in this system so I'm asking for advices on alternatives or maybe pro's and cons.


Any response will be appreciated.
Thanks

Drop the q9300 and get a q6600.. Oveclock it over the speed of the q6600.. feel free to ask more...

lunyone covered everything. However, I like the Antec TPQ 850W combo better for your build. The Antec EA 650W will do in a pinch though.

The 780i chipset is probably the better one, but that would run you more. We don't really recommend SLI here much... the nVidia chipsets are bad. Nothing wrong with your video cards though so you'll have to make do.

The bracket lunyone linked is not the right one... looks like they are out right now. However, you can get the 4-heatpipe version which is just as good, and use the linked bracket:

Hmmm ya when I looked it wasn't there but when I followed another link, there it was... odd.

Thanks alot for all the tips guys.

So as of now, this is what I've come up with at newegg.ca and boy...what savings!

Feel free to give me any further advice or tips
I'm still looking at possible CPU coolers as well

Alright sounds good. I'll take that into consideration. Thanks a whole bunch lunyone!

600w is more than enough. That setup wouldn't take up more than 420w.
