Update 9/28/2017I have reduced my review to two stars. At the time that I wrote the original review the card functioned beautifully. However, within a few months it started to hit a steep decline. Within a year I was experiencing many games crashing, working at single digit FPS,etc. The reason? Well, this card was developed, supported, and dropped like a hot potato. I've never owned a card with such short lived support. What's worse is that any card produced after this one is significantly more energy efficient. I actually traded this card for a GTX 1060 (6GB) and saw a lot of improvement. Basically, what this boils down to is a lesson. After THREE RMAs I gave up on ever having a stable GTX 780ti Classified. It's just never going to be a thing.Original review:This is based on my initial feelings about the card and only playing it on a limited number of games. I will update this review once I have had a bit more time to gauge its performance. The current four star review is not a reflection of the card performing poorly, but a conservative review that will probably be bumped up to 5 stars once I've had more time to play around with it.I have only owned this card for a few days, but I definitely put in the hours during that time! I upgraded from the Evga GTX 580 1.5 GB graphics card and definitely noticed a few improvements. However, whether or not this is a worthwhile upgrade from a card like the 580 really depends on a person's reasons for upgrading. If you are looking at purchasing a 4k,1440, or 1600 monitor in the next few years and already require a graphics card then this is a pretty great option. The card is pretty much only using about 1-1.5 gb at about 60% load and 50-75% memory (via the nvidia OC monitor) without any overclocking. Basically, there's a whole lot of room to run with this guy! So, if future proofing is your thing and you are looking at upgrading your monitor some time soon then this is a great option. However, the numbers show that for single screen 1080P gaming this card is so overkill that you'll probably squeeze a decade (alright, maybe a bit less :P) out of it before any games can touch it. The reason that I went for it is two fold: For one, I wanted to see what kind of difference the upgrade would make from a 580. For two, I wanted to give myself the option of going for a 3 monitor set up (I already have 2) or possibly upgrading one of the two to 4k, etc. and continuing to game on a single monitor. Options are good!So far as the 580 and 780 ti comparison goes, There's a noticeable difference in how smooth and beautiful everything looks. Far Cry 3 is a pretty amazing looking game when you've got a card that can max out all of the settings, or even if you can only run them at high/very high as you can with the 580 (no AA). I don't think that I would have had any problems with the 580 had I never seen what the 780 ti provides. The differences are minute and will only matter to people who have both cards sitting there to compare directly. My reference to "smooth" is not to say that the 580 is jagged and under performs, it is more of a reference to the smooth lines and little details like grass swaying, etc. that you won't really miss if you never see it, but is a nice addition for a higher end card.In summary, the 580 still performs extremely well, and it might well be another year or two before the differences between these cards for a 1080 screen is enough to force someone to upgrade based on performance issues. Also, the 780 ti Classified is larger than the 580 in every way. Make sure that you've got the space for it! I have posted a picture to show the difference in size from the "Front."One last note: I had a problem with Far Cry 3 crashing while using this card versus the 580. It was highly disappointing to get a card that should destroy modern games only to have it be brought to its knees at my first attempt to show it off. Fortunately, I found the issue to be with graphics settings that were not configured correctly. There was an abstract option to change from SSAO, HBAO and HDAO within the game and HDAO was selected. Based on my research HDAO is designed for AMD (ATI) cards and and HBAO is designed around Nvidia cards. Once I fixed this I haven't had any crashes at all. This might be rudimentary information for some, but I wanted to include it as a footnote for anybody that runs across this weird problem like I did. It sucks to spend so much on something to find out that it won't do the very thing that you bought it for!My basic setup:Processor: Intel 960 i7 (recently upgraded to 980x)RAM: 24 Gb of Corsair DominatorGPU: 780 ti ClassifiedPSU: 1000w CorsairCase: HAF 933ASUS P6X58D-E (1366 socket) (Upgraded to EVGA X52 Classified)Monitor: I only game on one 1920 x 1080 monitor at the moment
