That is the exact same card I just included in my new rig. No problems at all so far. I am convinced it is one of the best cards out there if you consider how much bang for the buck. No driver issues, preformance is fantastic (in my opinion), can run anything I throw at it maxed out,all for about 150 bucks. In regards to shadow issues some people have had with other cards, shadows are no problem with this thing.
Am talking about 5770, didn't realize this post was so far from the first one!
