What a pair of EVGA GTX TITAN SuperClocked video cards can do is truly amazing when overclocking is thrown into the mix. Coming off the disappointing results that was on offer from the AMD Radeon HD 7990 6GB when overclocked, what we saw here today was really amazing, with massive performance gains being seen in many areas.
When you spend in excess of $2,000 you expect some truly amazing performance, and you also should expect to not have to overclock the cards to get playable numbers. Besides Nexuiz at 2560 x 1600, you really don't have to. There's no denying at times, though, the 20% gains that are seen would indeed come in handy if you move to Surround Vision resolutions or a 120Hz monitor.
There's little to complain about when it comes to this kind of setup outside of the price tag. I think it's still fairly safe to say that when it comes to the $1,000+ setups, the HD 7990 6GB and HD 7970 GHz Edition in CrossFireX does look more impressive from a value point of view. CrossFireX, though, is not a perfect technology, and at the moment, overclocking isn't an option with some negative effects being seen.
Throwing a third or fourth video card into the mix is also going to push the numbers even higher. Looking at the performance we've got here today including the numbers out of some of the most intensive engines on the market it, it feels safe to say that you're probably better off not even looking at three or four way setups unless you're going down the path of multi monitors, or possibly a 4k resolution monitor.
Getting the kind of performance where you don't need to worry about in-game settings costs money - especially when you're talking 120Hz monitors with 2560 x 1440 / 1600 resolutions. The GTX TITAN SLI setup is indeed one of those setups that lets you install any game and know that within game settings maxed out, it's going to be smooth.
With some decent headroom with overclocking as well, you've got even more wiggle room when it comes to FPS in the future.
