Should i get the arctice silencer for my videocard?

From wat others have said my videocard is running a little to hot...i have the agp 6800gt and it usually runs idle at 55-57 celcius and goes up to round 70 when im playing games....so ? is is it worth buy this cooling thing for my videocard?

It might just be. There's other coolers out there, but this one has great reviews. There's even one that the guy said his card was running 65-70 at full load and dropped it to around 55. Sounds pretty good to me.

 

Posted twice, I only clicked it once. Well I'll edit it so it's at least different.

 

I've used those coolers before.
They're the Dogs B*llock!
Definately worth the money.
