Help building gaming PC

[geforces]

Hello,

I wish to build a PC primarily for gaming. I am not very experienced in most areas of computer hardware and I am looking for some advice.

As it will be a gaming PC performance is the greatest factor, but i want it to be a reasonable price ($600-$800)
I have found some parts that look good, what do you guys think?

MSI N460GTX Cyclone 1GD5/OC 1GB Overclocked Graphics Card
AMD Phenom II X6 1090T Black Edition
Corsair 4GB Dual Channel Corsair DDR3

One problem I have faced is that I know just about nothing regarding motherboards. I have read that combining the GTX 460 with a hybrid-SLI capable nVidia motherboard will improve performance. Is this a worth while purchase and what models of motherboards would suit my CPU and GPU ideas?

I am a bit of a newbie in computer hardware so any advice is greatly appreciated.

Do you have a monitor. If so what size ( res ) ? and do you have any other hardware or is this a ground up build. What games do you/are you going to play ?

I have a monitor with a resoultion 1680 X 1050 (it is a few years old)
My current PC is about 3-4 years old but was a good PC at the time, it was a pre-built system not made especially for gaming but is still OK.
I play games such as:
COD black ops
WOW Cata
Starcraft 2
Dragon age 2
and soon Crysis 2

My current graphics card (Geforce 8600 GT) can not play any of those games any higher than about medium settings.

As I am not very experienced in computer hardware I don't know what I can salvage from my current rig. I can list all specs later if needed.

all specs would be good. hate to suggest new hardware when all you need is to replace that video card. Do you need an operating system too ? ... or do you have a disc.... W7-XP-Vista ??

These are the specs of my current PC:

CPU: Intel core 2 duo (E6550) 2.33 GHz clock speed, 1333MHz FSB
GPU:256MB Geforce 8600 GT
RAM: 4GB (4X1GB) NECC Dual Channel DDR2
