No. Under no circumstances should you buy that.
You can do a lot better for that kind of money.
The i7 7740x is out of date and has been replaced by options that are better in almost every usage scenario. And the X299 platform is extremely expensive for what is ultimately a budget / mid-budget build.
Bear in mind there is a much easier and more convenient way to post specs - under the spec summary screen (which I think is what you screenshotted), scroll down and use the Post to Forum button. Then you can copy/paste the text. Saves us waiting for 30 seconds for the image to load on slow internet
What did that spec cost?
What are you using it for?
Gaming? What monitor and what kinds of games? Anything other than gaming? Specific software?
Are you streaming gameplay to twitch/youtube etc?
Well, link me a PC I should get... I need it for gaming.
