whats the difference between these two 8600gt cards?

I can't seem to find or understand the meaning of the differences between these two cards. Could someone tell the all the difference between them, and the advantages of one over the other?


A

GIGABYTE GV-NX86T256D GeForce 8600GT 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card - Retail = $140

Says it has Dual-Link dvi? what exactly is this?
Doesn't say anything about HDCP... does it have it?


B

GIGABYTE GV-NX86T256H GeForce 8600GT 256MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card - Retail = $125
http://www.newegg.com/Product/Prod [...] 6814125070

States that it has "HDCP".
Doesn't say anything about the type of DVI... is it dual link as well?



Thanks for helping me figure this out!

hum, then why do you think newegg has them for different amounts?
I checked the gigabyte pages, and it seems like the model ending in D has dual-link dvi (what is that???) but doesn't seem to have HDCP

and the model ending in H doesn't mention dual-link but does have HDCP.

So what am I to do?
I would like HDCP, but am I missing something with the cheaper card?

Thanks again.

Dual link DVI's are DVI ports that can drive large screen monitors
like those Dell or Apple 30" Cinema displays.

Some DVI ports are only single link.
I think the D version uses better power transistors?
