I have been out of the tech scene for some time and I'd like to replace the mobo/CPU/mem of my computer. I have only three conditions: -1. the total cost of those three parts is less than $300. -2. the mobo MUST have optical out -3. I'd like an AMD processor (as I have all the right fans and sinks for an AM2/3). I looked at NewEgg and TigerDirect, but I'm at a loss for what actually may be good. The machine is mostly an entertainment center, but it does gaming often as well. I currently have a Pcie 9800GT 1G Graphic card that would stay with the setup. Do you have any links to stores that would work to complete the set? Thanks.
