Hi !

Here my current HTPC rig :

Intel Core 2 Quad 9400
Asus P5B Deluxe
8GB de DDR2
Creative X-FI XtremMusic SoundCard
Gigabytes RX460 2GB
Logitech Z623 2.1 THX
Panasonic 42 inch G25 plasma TV

I use MPC-HC or PotPlayer to listen to my x265 1080p movie I got no problem at all ... the CPU almost sleep but when I try a x265 4K my CPU top the 100% even with my RX460 ... there is a way to use in a better way my RX460 to help my less powerful CPU to read 4K video file ??? or really my Q9400 is my bottleneck and I can?t think there is a way to read 4K x265 file on it ... if it?s the case do you have a suggestion for me about a good CPU + MOBO to update my HTPC.

My gaming rig has a i7 3770K with a ASUS Sabertooth Z77 mobo .... must I just swap these in my HTPC and upgrade my gaming rig with a new mobo + CPU + Ram ???
