Sapphire 5970 Toxic Review

Test Setup and Overclocking

An ultra high-end, extreme performance twin-GPU graphics card that costs a substantial amount of money. It's pretty clear that the most direct competitor for the Sapphire 5970 Toxic is the aforementioned Asus Ares and so we're going to be putting them head to head in our testing. The only differences between the two setups from when we tested the Ares to the Toxic are that we're using Catalyst 10.7, and the 980X is only overclocked to 3.6GHz.

Corsair Dominator GT @ 1600MHz
ASUS Rampage 3 Extreme
Intel i7 980X @ 3.6GHz
Corsair AX1200w
Windows 7 Ultimate 64 Bit
Noctua NH-D14 with Arctic MX-3
Sapphire HD5970 Toxic


As the Toxic already has a monster overclock we were surprised that we managed to coax a further 99 MHz out of it before it cried enough.

If we were cynical we'd think that 999 MHz is a very convenient number for the card to stop at, especially considering how easily it reached that point. However a 1 GHz 5970 should be more than capable of hammering anything we throw at it, especially considering it is 33% faster than a standard one and the standard 5970 eats games for breakfast.

Wow. I'd love one of those for my system! I didn't expect it to overclock THAT well!

By the way, I see the award images have changed? (atleast for the performance award?) I like it, looks nice Quote

Yes indeed the awards have all been updated to match the new OC3D logo. If you think the performance one is lush, wait til we bring the others out.Quote

great review but I really can't understand why in crysis warhead the asus ares kicks the ass of the toxic in the minima and average FPS even in stock clocks - what's going on here guys? Quote

Couple of things explain that. Firstly the Toxic had a few less CPU clocks to handle the Physx, and the Toxic is a 5970 whereas the Ares is twin 5870s.

So the CPU will account for most of it, and the tiny extra theoretical grunt of the Ares gives us the few extra. If you look back at the Ares XF results you'll see that Crysis is pants no matter how much hardware you have. So really take it with a pinch of salt.

A. Completely rip off the Arctic Accelero Xtreme
