Summary: Nice upgrade from my old Nvidia GTX 280 that came with my XPS 730. The installation went smoothly. Updates for the card worked fine. It works better with my 2 monitor setup than the 280 did. I recommend this card.
Summary: So far I really like this card for most of the games I play online and single player. Runs Games like Just Cause 2,Assassins Creed Black Flag,Skyrim,and Crysis 3 really well. The only problem I have encountered is playing Battlefield 4. I'm not sure if its the card or just the game itself but multiplayer has a small stutter at times on ultra settings but this might not be the card. Don't get me wrong it plays the game very good and may just need some tweaking.
Summary: Got this card on my rig right now, installation was a breeze. My system rating jumped from 5.7 to 7.8 for graphics subscore. Not a gamer, but do video and animation. Thought card is not approved by Adobe, but had to work around that by doing a simple hack, and now I have Mercury Playback Engine on Adobe PP working fluidly! Yipeee! Also After Effects raytracing works perfectly with this card, unlike the Intel HD 4000 on my i5 3570K. Significant upgrade I must say...
Summary: Since the manufacturer recommends at least 450 watts, and my XPS 8700 has a 460 watt power supply I was a little nervous on this purchase. Note, the Intel Core i7 4770 in my Dell only uses 84 watts as compared to the 130 watts on the CPU it replaces that was used in the XPS 8500. The maximum power required by the PNY GTX 660 is 140 watts. I needn't have worried.
