Need more info. What CPU, and what other components do you have or plan to use?
I don't know what I'll be using yet: a video and sound card probably and a lot of ram for browsing. Personally I think 2 cores will be plenty but we'll see. I'm trying to get information to make the best choices. As long as we can get the best video and audio for streaming content, and minimize lag while browsing. That's about it.
that really isn't calling for a $100 motherboard. you can get a sandy bridge pentium and a inexpensive H61 board for $160 total. btw, web browsing doesn't need much RAM, 4gigs would do it.
