I'm unsure about the graphics performance on a new HTPC. It's built with an A8-6600K which I think has Radeon 8570D integrated graphics. I also have an NVIDIA GT 610 card with 1GB of memory.
I'm having a tough time finding stats to compare these two to determine if I should use the card or the integrated graphics. The pc is just going to be used for watching movies, streaming content, internet, etc. Probably no gaming at this point.
