This doesn't go into the OPs mention of the problems with GTX 980 which better get fixed soon, but instead it puts some details into the *I can build it better for less*.
I think I can build it better. Yup.
I think I can build it for less. Yup.
I don't see how to build it better for less. There were / are frequent deals for xps 8700s for around $600 (core i7 ). I've not seen a parts list to do it cheaper.
So, for all those claiming to build it cheaper, here's your chance. Omit the PSU and graphics card since those are throw-away for anyone upgrading to a high end graphics card. Your budget is $600. Now please, build it better for less.
System must include windows 64 (7 or 8) and should include a keyboard and a mouse to be fair price wise.
the "crappy" Dell Mobo is Z87 chipset so it should be at least that with four DIMM slots.
core i7 4770 or 4790 / Z87 MoBo / 8 GB DDR3 1600 / 1TB 7200 RPM HDD / windows 7 or 8 / DVDRW / 2x USB 3 on the front (or top) 2x USB 2 on top (or front) with SD memory card slots, wifi (B-G-N)
here's my failed attempt to beat the price (along with my comments on why I picked that part)
CPU: Intel Core i7-4790 3.6GHz Quad-Core Processor ($289.99 @ Newegg) // cheaper today than a 4770
Motherboard: MSI Z87-G41 PC Mate ATX LGA1150 Motherboard ($79.99 @ Newegg) // cheapest Z87 or Z97
Memory: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory ($70.99 @ Newegg) // cheapest DDR3-1600 1.5V
Storage: Hitachi Ultrastar 1TB 3.5" 7200RPM Internal Hard Drive ($42.99 @ Amazon) // cheapest 1TB 7200
Case: Rosewill Challenger-U3 ATX Mid Tower Case ($51.99 @ Amazon) // just a cheap case that will work. hard to find much cheaper
Optical Drive: Samsung SH-224DB/BEBE DVD/CD Writer ($14.99 @ Amazon) // cheapest DVDRW
Operating System: Microsoft Windows 7 Home Premium SP1 (OEM) (64-bit) ($88.98 @ OutletPC) // cheapest listed
Total: $639.92 <------------------ but what? its more than $600
Adding Wifi, keyboard, mouse and an SD card reader.
