Hi All
From the HardOCP website Asus Stix 780 6gb vs Asus ASUS Radeon R9 290X DirectCU II @ 4K
Quote:
We take the ASUS STRIX GTX 780 OC 6GB video card and run two in SLI and overclock both of these at 4K resolutions to find the ultimate gameplay performance with 6GB of VRAM. We will also compare these to two overclocked ASUS Radeon R9 290X DirectCU II CrossFire video cards for the ultimate VRAM performance showdown.
End of quote
It is tough to choose between the two. I am not a fanboi of either card just a fanboi of advancing technology. Enjoy
