/*Review:*/ Sapphire HD 4890 Toxic Review

( -at -) Hi Tech Legion

/*Snippet: *"Just the other day, I went to a friend's house to fix one

of his computers since he was having a problem with his video card

crashing for no specific reason. The first thing I noticed as I walked

into his computer room was how much warmer it was than the rest of the

house. After commenting on that and shutting off his media player I

heard a high pitched whining sound coming from his case. I asked him

what it was and he told me he had to keep his ZeroTherm VGA cooler at

100% or his video card would freeze. Right there I knew that heat was

his issue and immediately went to check his heatsink for dust build up

and to make sure that he had some decent heatsink paste on the GPU. Both

were fine but he did have an older ATI card and was overclocking it.

The Sapphire HD 4890 Toxic is a preoverclcked ATI 4890, which comes with

Sapphires Vapo-X heatsink and fan. The Sapphire HD 4890 Toxic is built

around the ATI RV790 graphics processor which is a 55nm chip has 800

streaming processors. The Toxic is one of three overclocked versions of

the HD 4890 that utilize the Sapphire Vapo-X heatsink and fan, cooling

solution and it is priced in the middle of those two other cards.

(Atomic and Vapo-X)"/
