Building a system for streaming TV and basic home PC use. I'm using an AMD A10 Trinity with radeon HD7660 built in, BIOSTAR Hi-Fi A85W FM2 AMD A85X MB. I already have an EVGA 02G-P3-2629-KR GeForce GT 620 2GB 64-bit video card. Would that card work with the Biostar's sound components or not? also would I benefit from that EVGA or is the Onboard Radeon better?
