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.
Summary: So i built a custom rig and i had been told to go with a 2gb model or just newer models in general but i didn't quite wanna spend the extra $50-$100. So far i have had this rig for almost 3 months and this video card has performed more than well enough for me, every game i have thrown at it has been flawless at the highest settings as far as graphics go. Skyrim, Sims 3, Assassins Creed 3, etc. It is an excellent video card for the price and has exceeded my expectations.
Summary: After it's first use, it just overheated or something. When it did work however, it was dead silent, very fast, and worked perfectly for my steam games. I probably did something wrong when installing it.
Summary: This card was okay. but it wasn't what I was looking for. I believe the Geforce cards perform better, and the EVGA brand provides better support and build quality. I'd look elsewhere unless you are stuck on an ATI card.
