I've been waiting for a deal on one of these and looking around. It basically has the same specs as the hd60s, which is what most streamers and youtubers are using. This pro version is an internal card instead. It requires an open pcie slot in your pc. It offers a higher bitrate than the hd60s though.
Record and stream 1080p gameplay at 60fps with a 60mbps bitrate.
Note, eligible American Express cardholders with Rewards Points may save an additional 20% off when redeeming a minimum of one point ($0.01) towards this purchase (details here), making the price $ after the discount.
