What about a 6950 Tri-fire? That would be ~$900 and would be pretty darn close to the 6970 tri-fire and cost a decent amount less than both a 580SLI or 6970CFx3 system.
Get 6970 CF and put the rest towards a better monitor.
6970 Tri-Fire is the way to go then :thumbsup:.Well pretty happy with the current monitor-want to go eyefinity with 3 of the Hanns G's.
