I would like to see 690 card in this test, because there are people saying that 690 is better than Titan, or 3 780s as it will perform 2 Titan, any test for those?
I quote to me from another site when i was getting Titan:
"I'm not entirely sure I'm following your logic, if there is any, but to each his own. Was simply offering a bit of advice while you had the chance to swap. I was just under the assumption that you bought the Titan for performance. Is this assumption correct? It seems you think that I think value is a tradeoff from performance. That is not the case. Value is directly correlated with performance, actually. With performance in mind, the 1000 you spent on the single Titan is not the best performance solution that you can get for 1000 USD.
Example:
1 Titan = 1000 USD
1 GTX 780 = ~92-95% of the performance of Titan, the OC'd partner models are actually outperforming Titans = 650 USD
2 GTX 770s = 800-900USD
1 GTX 690 = 1000 USD and is 5-15% faster, depending on the game.
Two GTX 770s, specially overclocked will destroy a single 780 and the Titan.
2 Titans = 2000 USD
2 780s = 1300 USD
3 780s = 1950 USD
2 GTX 690s = 2000USD
These two solutions in most reviews, due to variaton in SLi scaling, perform nearly identical, so therefor spending the extra 700 on the Titans over the 780s is a waste, and you could spend it elsewhere in your rig for even more performance. You can even buy 3 780s for the price of two Titans. And if you're intent on dropping 2 grand, even two 690s will outperform the two Titans. Best choice in this niche? The two 780s. Best choice if you're intent on ignoring value and spending 2000? The 3 780s, followed by the 2 690s, then the two Titans.
So what I'm saying is on a performance mindset, buying a Titan these days is simply a purchase for novelty. The card does not fill in any performance space at all, because at or around 1000 USD, all other options are better. Two 780s for 300 more, Two 770s for 200 less, a single 690 for the same price, even two GTX 670s would perform right there with a Titan and cost 350 less. ALL of those options are the better buying choice."
Any clue or comment?
