Sapphire Toxic HD 4890 Vapor-X review

guru3d.com — We test the Sapphire Radeon HD 4890 Toxic Vapor-X edition graphics card. Armed with a nice vapor chamber heatpipe based cooler and with it's clock frequency locked at a steady 960 MHz, this little beast is ready for some serious gaming action. And it doesn't stop there though, even the nice phat 1 GB graphics memory is clocked higher at 4200 MHz. Jul 2, 2009 View in Crawl 4
