Summary: Go for the Core 2 Extreme QX9770. The QX9770 is the king of the 775 socket, though this one here I bought is the king of the 1333Mhz front side bus speed on the 775 socket. The QX9770 has a front side bus speed of 1600mhz, hence the king of the 775 socket.
Summary: Wanted to breath some new life into my aging computer, so I found the best processor that my board would accept, this is the one. The dual core that I was using before would regularly run at 100% and eventually overheat, this one stays cool and I've yet to use more than 70% of its power.
Summary: I bought my Gigabyte motherboard several years ago and opted to go with a more expensive model with room for expansion. At the time, money was a little tight so I only bought 2 GB of memory and went for a 32-bit dual core CPU.
