For what reason - Game (mostly WOW) and adobe software (Illustrator, Photoshop, etc.)
Budget $1200 to $1500
I know that GPU and Ram is pricey right now but I'll worry about that later when it goes down. Want to have a good PC that can last 5 years or so. Need help with parts, etc.
Have you reviewed the builds of the month Chaud throws together each month? It's a pretty good baseline and Narwhal sounds about where you would want. Can't link cause im a pro-lurker.. but it's linked from the main page in the top banner.
1070 would be the way to go.. But the current market has them just over your upper budget.
