I have decided to build my own comp. tell me what you think...how will it match up?

The motherboard and CPU you selected are not compatible. The motherboard is for an Intel chip and not an AMD. If I was building this machine, I would skip the Blu-Ray for a regular, cheaper DVD writer and spend a little more on the video card. At current prices, I would go with a Nvidia's 9800GT or ATI's 4850. Both cards can be had at less than $100. Check Newegg.com.
