so i started buying parts for a rig im building this is what i bought:

Is there a better or different motherboard i could get?

Motherboard: Asus P9X79-E WS
Processor: Intel Xeon E5-2650 2.0GHz 8 Core Processor, 20MB Cache, Sandy Bridge EP Socket 2011 with Thermal Grease
Ram: Avexir Core Series (Blue LED) 8GB Kit (2 x 4GB) Dual Channel 240-pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Module AVD3U16001104G-2CW
Power Supply: Evea G3 1000w
Risers: 6-Pack V006 PCI-E 16x to 1x Powered Riser GPU Adapter


Thats about $650 without any cards.....? good choices?

It would be nice to have a list of hardware lol

But its sounding like i should get the RX 460's and get all my money back in 2 months then maybe sell them and get better ones.......but is the equipment above good to do that with or could i have bought cheaper equipment up to too?
