I think Intel/Nvidia is currently the better choice?

How much RAM/CPU/GPU ratio to not have 1 part too powerful and go to waste?

Or is there a laptop that's is as capable with not too much a price bump?

what kind of video editing and what is the budget?

Just for home use, but a capable one.

Budget probably $2000ish.

What would you build if budget isn't an issue.

Parts has to be readily available to buy. Not some crazy stuff that you need to have special order.

If you have money to burn just get a workstation.

you mean like newegg/ amazon right.

Or has to be local, like what you have fry's electronics/microcenter.

I'd reccommend any I7 you can afford. (unless you overclock then theres generally an overclocking sweetspot).
For videocard if it's just video editing you don't need a 670, a 660 ti or ati equivalent is fine (Probably even lesser models are fine too). Unless you want to do ultra gaming.

Again, obviously the more you spend the better it will run, but for video-editing for only home use. Any I7, with 8gb of ram, and nvidia card Will be fine. I don't think you even have to spend 2000 grand to get a pretty good videoediting one. But again

If you had unlimited budget dual xeon's and like 6000$ quadro's is probably the way to go.. but that would be like 20 grand :).

I wouldn't recommend a laptop. As any powerful laptop has a significant bump for equivalent performance (especially at that range)

Shouldn't Quadro FX be the better choice instead of GTX? This desktop will not be for gaming.

So, an i7 with 16GB RAM? Since RAM is quite cheap nowadays. Would 32GB RAM be useful or is that going to waste?

16GB Ram would do it.

But aren't Quadros too expensive for your budget?

You can SLI two 660s.

So, a dual GTX is better than a single Quadro?

I heard Quadro supposed to be great for video production. I know nothing about it, though.

What applications will you be using? For professional applications you'd generally need a quadro card, which are more expensive than standard cards.
