Laptop faster than i7 6700HQ

[FastRunCPU]

Hello everyone,
I am looking for a 15" or 15.6" laptop with a fast CPU.
I will use it to the numerical simulations, data mining... So it needs to have a fast single core option.
I will not using it for gaming, video editing,...
I will use it in different meetings with clients and supplier,s so I having a colorful laptop with bright keyboards is not what I have in mind.
I have checking Dell XPS 15 model; but I which alternative I can have to i7 6700HQ.
My bugdet is aprox. 2000$.
Thank you,

You need a Dell precision 5510 or 7510, for 2000$ comes w/ i7 6820hq but for 2300$ comes w/ Xeon E3-1505M v5 and if you don't care a Refurbished or Scratch & Dent laptop, you can find this version in 2000$ or less in the Dell Outlet

Have a look at xotic pc. They should have a laptop for you as they can customise everything to your liking.

Check DigitalTigers.com, they deliver trading workstations, PC´s, Laptops and Multimonitor Layouts. I develop Trading Systems using genetic algorithms and Neural Nets and backtesting is a major cpu power troglodite. By the way, the first choice they offer is DELL's 5510. I have one with XEON processor and maxed to 32 GB. Its a UFO
