Here is one list I've done for another person which as a similar requirement as yours. Check it out.
EDIT: The list has changed. Seeing that you will be running a multi-monitor setup and you are reusing parts. Take a look at it again.
If you don't do DC projects (which puts 100% load on your GPUs and/or CPUs 24/7), or extreme benching, it will be fine.
Just watch out for the cooling for the PSU.
Athlon II X4 630 - $95.99. My friend, today is more than half way through the 2010. Building a gaming computer without a hardcore is somewhat laughable. Shell out 15 bucks and a quad. You will like it.
Mushkin Silverline DDR1333 4GB $79.99 - Don't understand why memory prices are bitchin...
Phenom II X6 1055t - $197.99 Six core and overclocks well. This thing can last you for a long time.
ASROCK 890FX DELUXE3 - $149.99 Very nice 890FX board for the money, it has 3 16x slots which will give you lots of graphics potential. It had also received a lot of favorable reviews, too...

Antec EarthWatts 380W - #39.99 The PSU will be able to handle your rig without breaking a sweat, especially with its 80PLUS BRONZE rating, this thing...
By the way, don't get that GTX470, especially with the stock cooler. That thing is an oven.
Get the MSI GTX470 Twin Frozr - $319.99 after REBATE. Will clock like crazy if you overvolt it, and it has the best cooler out of the box you can ask on a GTX470. Also, it is factory overclcoked.
If...
For the price right now, don't get the H70. Also, the H50 isn't that much better when talking about price/performance.
If you are looking for the best performance out of the box, get the Thermaltake Frio for $59.98. With two high-cfm fans included, this thing beats most of today's...
According to my list above, it totals as $1232. Leaves you about 200 bucks for a power supply.
