Can i get some help with my new rig please?

Ok, im gunna be building a pc on my own for the first time, have seen it done and have been doing a bit of research for it. so far i have come up with the following parts. I already have a STC-T01 Stacker case, a Silverstone OP1000w power supply & a PetrasTech Elite Watercooling kit (With an apogee GTX (Which i have bowed) + MCR 330). This rig is going to be used 99% for gaming. Im looking at a budget of around $5000AUS (Which is about $4150US) I know some parts arent out yet but im hoping they will have a juneish release <fingers crossed>
Any help is more than welcome

Mobo - EVGA 680i or Asus P5N32-E SLi (Any help here would be great but the mobo has to be true sli [2xpci-e 16 with a bandwidth of 16x16])
CPU - Im thinking of getting either a QX6800 or getting a e6600 now and waiting for Penryn to come out
Ram - 2Gb Team Xtreme PC6400 DDR2 800Mhz (3-3-3-8) or would 4 GB be more worthwhile considering im going to be running Vista?
Vid Cards - 2x 8850GX2/8950GX2 (Whichever name Nvidia decides upon)
Optical - Pioneer 212D
Display - Im thinking about getting a Samsung 244T. LCDs are new to me so any ideas here would be greatly appreciated. From what i have seen though i might be better off sticking with my 19" CRT viewsonic
1x250 Seagate Barracuda 7200.10
1x500gig Western Digital

You're basing your system around rumored products expected to come in late Q3?

That 19" CRT would be a waste of a single 8800GTX, so why would you run two "8850/8950s" on it? If there ever is a GX2 card, it'll have to be 65nm making it an 8950.

One of the mainboards you are investigating using (eVGA 680i) is in fact the nVidia reference board. All of the reference boards are made by one contract manufacturer, and then branded by board partners and sold. If you decide to go with the eVGA board, also check prices on 680i boards from BFG, XFX, ECS and Biostar (supposedly, altho its not on their website yet). Snatch up whomever is cheapest that day, because the boards themselves are absolutely identical. Foxconn also has a board that appears to be the reference board, but thats just my conjecture, I dont know this to be true.

I personally favor the Gigabyte 680i board (quad gb lan, 10 SATA) or the MSI board (4 PCIe 16x slots, altho with your build only three would be active, onboard X-Fi from Creative). Both are expensive and very difficult to find, today.
