Review: Sapphire Toxic X1900XTX 512MB graphics card

Running high-end graphics cards quietly at peak frame rates is a major problem.

Sapphire has addressed this problem with its Toxic X1900XTX graphics card, which loses the huge heatsink and fan of the standard X1900 XTX reference design, and gains a water block and separate water cooling device with a smaller and quieter fan.

Impressively, it’s also factory overclocked with a 675MHz core and 801MHz memory (1,602MHz effective) clocks as opposed to the standard 650/750MHz clock speeds.

The card itself is still a two slot job, but you Sapphire has thoughtfully made the water pipes long enough to use any available PCI slot.
