I am considering getting the Oculus Rift when it comes out. I looked at the system requirements and decided that it is likely time to upgrade my rig - or get a new one.

My current specs are:

Pre-built PC name: HP Pavilion p6-2300t
CPU: Intel Pentium G645 @2.90GHz (Sandy Bridge)
GPU: AMD Radeon HD 7450 1GB
RAM: 8GB Dual-Channel DDR3 @665MHz (4-4 slot arrangement, two slots on mobo)
Mobo: Foxconn 2ABF
HDD: 465GB Seagate ST500DM002-1BD142 (SATA)
Optical Drive: hp DVD-RAM SW820
OS: Windows 8

If you think I should upgrade anything, you can give me suggestions about what to replace; make sure it fits my mobo though! Otherwise, let me know if you think I should buy the rig below instead,

Pre-built PC name: Chillblast Fusion Quasar $748.59
CPU: Intel Core i5 6200 @3.60GHz (Skylake)
GPU: AMD Radeon R7 370 2GB
RAM: 8GB DDR4 @2133MHz (2-2 slot arrangement, 4 slots on mobo)
Mobo: Gigabyte Z170XP-SLI
HDD: 1000GB SATA SSHD 7200rpm Hybrid Drive
OS: Windows 8.1 (but probably will upgrade it to 10)

DO NOT GET WINDOWS TEN OR YOU'RE GONNA HAVE A BAD TIME

I would recommend a new system.  The costs VS benefits involved in upgrading your current HP system are not worth it.  The pre-built PC you've specified is pretty decent, however I'd recommend upgrading the R7 370 to something a little more future proof and making sure the power supply is a good quality 80+ (550W minimum).  If your going to spend that much on a new system, you may as well spend the little extra and have a system that will last longer.
