There is two ways at looking at it, if you buy a TV for $1000 or a 32" Monitor & speaker to watch TV on, Swapping out the Hifi as well. you replace it with a media center/entertainments system.

I have kids and with all the businesses that I run I dont have alot of time on my hands myself.
But then Im pretty rashional with where my money goes and why. So with that said.
If you buy a average PC it will need replacing or upgrading to its limits and replacing. What I am saying is add 50% more performance after a year or so for around $200.00 (it makes sence dosnt it?)

I recon that you can build that system for less than $860 + shipping.
I know this as I am looking at the prices of the lot from new egg, (less two hard drives and a lesser GPU together with only a single gig of RAM) I didnt cherry pick by price either.
On the list was:
Gigabyte Dual Processor EATX mobo
EMT 604 3.0Ghz XEON CPU
Corsair 1 GIG DDR400 (match mobo)
2X 160G Deskstar HDD's SATA
X300 Pciexpress GPU
Antec 500W PSU (didnt find the ESP which is required but is the same price)
Full ATX Case.

I know what you mean you with video editing eating away at time, Put it this way I just updated my system for about £270.00 and cut my editing and rendering times by 70%

Heres a few money saving tricks.
Overclocking offer speed and performance at cut prices.
A Nvidia 6200 will unlock giving you all the pipes tha tthe 6600GT has and will match its performance, the 6700GS also unlocks, the X850GTO unlocks.

All processors should give you 20% more performance, AMD are better as they run cooler.
RAM will give you a few extra MHZ = PC3200 gives you PC4300.

So you can work around a budget when perfromance is concered.
