I thought it would be fun to have a non-660Ti-biased debate of which graphics solution is the best for the money (don't only account for FPS per dollor). Let's ignore 1920x1080, considering these graphics solutions are intended for high resolutions. Let's focus on 2560x1440/1600. Let's also stick with the 4GB 680s (including the Classified), considering 2GB is not enough for higher resolutions with medium to high antialiasing. Note that both solutions are very similar in price (3 680 Classifieds are $1800 on Amazon currently).

Round 1.. FIGHT!

I believe the Titans scale better and 2 should be plenty and have lower power / heat so I'll go with that.

Hmm how about 3 way 7970's for around $1400 (they are runnin about 450-475 each and this before tax& shipping) and then sell then two of the game packs for $50 each so abut $1300 total.

Ok, that was kinda Troll reponse, that being said I would depend on the game though if that was my only choose I may lean towards two titians, if you consider the power needed to run 3 680 not to mention the noise generated the Titains seem like a better choose if your starting fresh.

You get half of the vram with the 3-way 7970 solution, which actually makes a difference in a few games currently out. Hitman Absolution requires well-over 3GB of vram on 2560x1440 with MSAA x8 on some levels. I'm not quite sure what the comparison is in performance between 3 GTX 680 Classifieds and 3 HD 7970s. The Classifieds are noticeably more powerful than a reference 680, and are clocked a bit higher than the Superclocked cards.

The Titan scales better than any of these cards though. In some games, I've noticed over double the performance. I guess the real question is going to be 3-way SLI Titans vs. 4-way SLI 7970. You're maxed out with 4 7970s, as you cannot add a 5th. You still have a slot for a 4th Titan, but that's unfair considering we all know that 4-way SLI Titan is the best solution in terms of overall performance.

The above link actually compares 2 Ares ii's and 3 Titans, with the Ares IIs coming ahead. However, the Titans are running at stock speeds, whereas the Ares IIs use liquid cooling and are essentially overclocked 7970 GHz editions. The Titan will overclock automatically if you have Precision X running, and you'll get some significant gains (i.e., 2-way SLI Titans on Heaven 4.0 2560x1440 maxed w/ MSAA x8 will get about 60FPS, then with Precision X running you'll get 70FPS, pretty big gain without any manual overclocking as GPU Boost 2.0 will do that automatically with Precision X running). Thus, I am confident that 3 Titans will push beyond 2 Ares IIs with Precision X running, and this is all on air. They're exactly the same price I believe ($3k), so this is probably the most interesting comparison.

I say quad SLI 680's would be a fairer fight against dual Titans, that way both rough equal out to $2000.

Personally, would go for the Titan's given the chance. Less power consumption, heat output and it seems to be a much cleaner solution. And far more importantly, you save some big bucks in the water-cooling department (because who isnt going to put them under water :lol: ).
