I am getting a new system with a DH55TC main board and an i7-860 processor. I wanted four cores and none of the four core chips have built in video. I would like to get some suggestions for which external video card to get. Are there any that can tie into the video connectors on the DH55TC? My applications are mostly business or number crunching so I don't need a super high-end gaming card. I am mostly interested in stable reliable operation with the DH55TC and if any boards can integrate with the built in connectors. I'll be running W7pro 64.
