Wait, you didn’t get my consulting bill of $500!
Seriously, looking at the Dell site, get the $799.99 XPS 8700. It’s got the Core i7 4790. It’s really $749.99 after the coupon.
I rock an XPS 8700 (highly upgraded), and I love it. It’s fast, very quiet (especially if you stick it under your desk), and it’ll crunch through data like a dream. See this thread
