I emailed you the cart from newegg.com
This is just a normal workstation I build for customers. Not a gaming rig, but with a better video card it can be.
I buy parts based on warranty. So the hard drives have 5 year, memory is life time, video card, motherboard and CPU have 3 year and the power supply has a 7 year
You will see 2 hard drives in the cart because I always do systems with Raid 1 (Mirroring) So one drive stays a mirror image of the other.
Wifi card you can simply buy and add to one of the pci slots. They dont cost much, or you can even get a USB one.
The only reason to wait for DDR4 or 5 is for the pure gamer who wants to squeeze every bit out of the system for speed and frame rates. The currently memory moves so fast that you cant even notice anything in Windows from the different memory types.
Heck, the lowest end DDR3 does 6.4 GB/s
http://en.wikipedia.org/wiki/DDR3_SDRAM#JEDEC_standard_modulesThe higher speeds get up to 17 GB/s
So these types of speed only really matters in heavy games and such.
If you wanted a gaming rig you only really need to replace 2 parts out of the list I sent you, a better video card and a bigger power supply to handle the new card. I paid $400 alone for my gaming card in my system and then got a 750w gold certified power supply.
