Please tell me what you believe is a safe overclocking speed, this card apparently has an amazing onboard heatsink and great overclocking capabilities...and ive heard of it being run up to as far as 520 by normal cooling- given my cooling system what do you believe is a safe, running speed for the card- only safe, certain answers that wont fry the card please! thanks in advance

what brand is it? a link would be lots of help, can't determine the overclocking potential without specs and brand. the 5900XT in GENERAL overclocks nicely, but some brands will be far less flexible than others. and you haev to find out what type of ram chips it uses...every brand is different with what type of RAM chips it uses.

Ive been told by several its easily overclockable to 5950 status, at a speed from 500-600 mhz, possibly more if i set up my fans right.

it looks like a solid card, but i can;t find anywhere overclocks of core higher than 400. its got good reviews though, stock of course. i would also consider the Leadtek 5900XT...it is as well a huge overclocker. http://www.newegg.com/app/viewProductDesc.asp?description=14-122-183&depa=1

The XFX one OCs nicely ... just remember case cooling doesnt mean crap when it comes to vc cooling
