Pros: I upgraded from a single 4850. It went flawlessly. It is quieter and my case runs 15-20 F Degrees cooler. I run Vistas SP2 and Dual core 3ghz with 4 gig ram. Core came stock at 820 Mhz and Mem at 1100. The games I play show dramtic differences. LOTRO, Starcraft 2 and Civ 5 all on max setting with AAx4 run smoothly, it is like I am playing new games. Dir X 11 is worth it IMO. Great card, exceelent Xmas present. The wife said NewEgg exceeded delivery expectations. This was an Xmas present, my wife has limited computer knowledge, she said NewEgg was a great place for her to shop.

Cons: Missing HDMI adapter that was supposed to be included.

Overall Review: I am terribly pleased. Best Xmas present I received this year by a far margin. Any LOTRO players out there, no stuttering 1920x1080 ultra settings, everything enabled 21st Hall names up, AAx4 tons of players runs silky smooth. I LOVE IT
