Though the [ برای مشاهده لینک ، با نام کاربری خود وارد شوید یا ثبت نام کنید ] doesn’t make a ton of sense on its own in light its higher price and odd spot between the GTX 780 cards, if we want to move into 4K gaming and the extreme load it presents, a pair of 290Xs becomes a very tantalizing option. Thanks to AMD’s XDMA engine the 290X has no problem scaling up to 4K in Crossfire, taking AMD’s decent single-card 4K performance and scaling it up to something that allows for 4K without the quality compromises. Considering 60Hz 4K monitors still run for $1000+, it doesn’t make any sense not to pair such an expensive monitor with anything less than a pair of 290Xs.
Of course the Radeon R9 295X2 deserves a mention here. As we discussed in our recap of April, AMD’s recently launched dual-GPU flagship card offers all of the performance of the 290X in Crossfire with much better acoustics and in a smaller package. Since our guide is based first and foremost on price/performance our primary recommendation for this bracket is going to be the 290X CF, but if you can make the steep climb to $1500 the 295X2 and its liquid cooler is a very impressive product whose vastly improved acoustics make 295X2 a superior option to 290X CF.
Meanwhile the GTX 780 Ti in SLI is also going to be a viable alternative here. From a performance perspective it will trail the AMD setups by 5% or so at 4K, so while it can’t match the AMD setups hit-for-hit it doesn’t significantly fall behind, making it practical to get similar performance in the NVIDIA ecosystem. The catch is that at $1360 for the dual card setup it’s closer to the 295X2 than the 290X CF in price, so it doesn’t have a distinct sweet spot on price or acoustics like either AMD configuration.
