You will want to use gpu offloading I assume, I have read that nvidia are better as you can use coreavc 2. It seems you need at least a gts220, I think the gts430 is a good choice as you will be able to run better filters etc though ideally you want a passively cooled one for obvious reasons. Then there is nothing wrong with a 775 dual core with 2gb ddr2. Though I have read you can us the gpu in the i3 or i5 for gpu offloading, but I have no knowledge of how good it is. Though I guess you will want more cpu power if you encode.
