All,   
Been playing DCS for a while, and am now looking to upgrade my rig for better performance.  My current rig is:   
AMD Phenom II X6 1090T Black Edition 3.2GHz 
ASUS M4A79XTD EVO 
SAPPHIRE  Radeon HD 6850 1GB 
4GB RAM   
I am looking at spending $500-650 on upgrading my rig.  I've been an AMD fan for a while, but have no issues with going the Intel route as long as the price is right.  I'm considering either the AMD FX-8350 or the i7 3770k.  I know the i7-3770k outperforms the 8350, but is it work the $129 price diff?  I could use that to buy some MFDs (already have a TM Warthog, TrackIR 5, and pro rudder pedals).  Will most likely upgrade the RAM up to 8 (unless you think 16 is safer).  The video card is a little old, but I believe my current bottleneck is my CPU.     
Thanks for any recommendations!
