Summary: I'm a linux user so "gaming" is often a hard subject. With the SteamOS on the horizon I decided that I might see what I could do with the last generation's technology. This card is perfectly good for "Good Enough" gamers like myself playing Steam Games. The card is also cheap enough to put into CrossFire if you already have another HD7700. Dota2 works just fine on Medium/High Settings at 1080p. Rogue Legacy works just fine on High Settings at 1080p.
Summary: This card is amazing for entry level gaming, I usually play most games at medium to high settings (some maxed out). I bought this card as refurbished so I wasn't expecting holy grail performance in overclocking and build. In overclocking I got 1100 core and 1250 mem which is better than what I was expecting. Build quality looks okay but at getting around 70% fan speed I believe I hear the fans hitting the fins on the heatsink at times.
Summary: This is a decent graphics card to own, but if you are not running a rather new monitor or TV, then dont expect to use the HDMI option off it. I have a slightly older model Toshiba 32" TV and it is not rated at 1080i. Because of that fact, this graphics card just does not want to work off my TV.
Summary: the MSI radeon 7770 OC edition is a beast of a card blasts through 85% of modern games on max setting would recommend for enthusiast and beginner alike. only problem i'v noticed with the card is if you take advantage of its massive over clocking potential for too long the card will crap out and blue screen u if u try to use it there IS however! a easy fix for this.
Summary: This was a significant improvement over my 256 MB card that came with my Mac Pro and support for Mini DVI and HDMI is a plus. Looks great paired with my 27" Apple Cinema Display. To the best of my knowledge, the native driver support for these ATI cards became available with Mountain Lion OS X 10.8.3. There are other ways to have the drivers install but your best bet is to have the latest version of OS X on your machine before installing this card.
Summary: I purchased this graphics card and sadly I cannot play Guild Wars 2 with it. It's not a super high end card but I expected to get more than 15 frames per second while playing a game like Guild Wars 2. Even with the settings on low I am still getting poor performance. It could be the games optimization but I only bought this to be able to play this game, and I am sadly still unable to do so with this new card.

Summary: I picked this graphics card after about spending 4 hours doing research on specs, as well as customer reviews and wow am i glad I chose this card. I installed it myself without any knowledge of installing graphics cards in a desktop and it went off without a hitch. So very easy installation.
