New $1000 Rig

I am hoping to take advantage of Newegg's deals by building a new rig.

I do MOD games & use Unreal Development Kit, so I am using a 1440x900 DVI (main) + 1366x728 HDMI (TV). I also edit videos with Sony Vegas, model with Blender, & Game (see gfx card).

My budget is $1000, which includes Windows 7 & Monitor.

Here are some things I know I will want.
Good Graphics Card, along the lines of at least a 4870 or 5770. (Crysis (WARS/WARHEAD), C&C3, Assassin's Creed, Bioshock, Far Cry 2)


GPU Decision

I'm trying to decide the following:
ATI 4890 or 5770:
4890: $169.99 http://www.newegg.com/Product/Product.aspx?Item=N82E168...
5770: $162 http://www.newegg.com/Product/Product.aspx?Item=N82E168... (CHEAP)
$164 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The 4890 seems to have about an overall advantage of 10 FPS (IMO) right now. I'm trying to decide if Eyefinity, DX11, & better drivers in the future are going to compensate for 10 FPS NOW.
If I choose the 4890 it will be a clear choice, a 1GB XFX card for only $169, for the 5770 I have 2 choices, I prefer Sapphire but only at the same price, the cooler between the HIS ($162) & the Sap ($164) seems to be different, to me a better cooler + overclocking can make up $2 of differences.
Of course, that's not all. There's a combo deal.
Zalman 660W PSU + the XFX 4890, the combo discount is $45, quite a lump

CPU Decision

I'm deciding on either a i5 750 (with aftermarket cooler + OCing), or a Phenom II 9X5 (965 or 955)
The i5 720 is $199

The Combo Deals really add a lot of confusion & decision making. There's so many paths.


RAM (updated)
Min is DDR3 - 1333, DDR3 - 1600 if it fits within cost. Looking for 6 GB if possible (Sandbox 2 & UDK can gobble 3+ GBs of RAM when building maps), 4GB is the absolute min. I would rather have slower 6 GB than faster 4 GB if it comes to that.

Shellshocker

Monitor
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
23 in, 1920 x 1080

I long for a 16:10 monitor (1440x900, 1920x1200, etc) but I am not picky, I chose that monitor because it is on the XMAS deal

I hope for a lot of suggestions & comments, I VERY open to all suggestions.
My limit is $1000, but cost is very important, I hope to drive the price down to about $900.

Thanks! I'll update with more info!

Update: I am intending to OC on air (no H2O, etc), I'm looking for a moderate OC (about .4-.6 GHz for AMD, .6-1.4 GHz for i5 750.\

Update 2: I might drop in another card for crossfire in a year or 2, since PCI-e 2.0 X8 equals PCI-e 1.1 X16 I don't need a full 32 lanes for CF.
