I just did a price comparison with an ibuypower.com pc, and the same parts from Newegg. I used their "top dog" PC (that's not the name of it). Consisted of a 980X, all-in-one water cooler, 6GB DDR3-2000, 2 5970's in crossfire, Asus Rampage III, Blu Ray burner, games, mouse, keyboard, headset, SSD, 2 1TB drives in raid, 2 27" Spectre monitors, Corsair PSU, CM HAF 932, ect. ect. and the works from ibuypower.com (sleevings, warranties, goodie bags, ect. ect.) It only came up to be $700 more than newegg, which if you think about it, isn't that bad. You get a 3 year warranty on everything, multiple goodies from the bags you wouldn't get elsewhere. A fully built computer, ready within a day, and shipped out the next day. I'm not saying all that is worth the extra $800, but rush orders, and next day shipping at newegg was still pretty up there too, at $300.
Doesn't have much to do with the topic, but I thought it was rather cool to know, they're not jacking up their prices nearly as high as their competitors.
