Attention hardware enthusiasts, our in-house graphics card gurus have just published our AMD R9 295X2 and XFX R9 290X DD TriFire review. Run, don't walk, on over and see what all the fuss is about. Will adding a single AMD Radeon R9 290X video card to the AMD Radeon R9 295X2 work? Will you get triple-GPU performance, ala TriFire CrossFire performance? This just might be a more financially feasible configuration for gamers versus QuadFire that provides a great gaming experience in Eyefinity and 4K resolutions.
