Four R9 290X-class of GPUs go up against three GTX 980s. AMD took a modicum of umbrage at our review of the Gigabyte WaterForce graphics behemoth. Sure, three overclocked GeForce GTX 980 cards are undeniably fast and offer good gaming at the ultra-enthusiast 4K resolution, they said, but, priced at an eye-watering £2,499, WaterForce hardly represents value, right?

The value sentiment certainly rings true, especially as a trio of air-cooled GTX 980s can be purchased separately for under £1,300. Yet there's now reasonable value in this extreme segment from the AMD camp. Savage price cuts on the dual-GPU Radeon R9 295X2, now available for sub-£500, brings it very much into play. A single Radeon R9 295X2 puts up a good showing against the three-GPU WaterForce, we noted, so what could two do? A total of four R9 290X-like GPUs for under a grand is more like it, and AMD partner Sapphire obliged by seeding us a second card for four-way CrossFire shenanigans.
