I was thinking about buying this 8800 GT but then I noticed it has a
6pin PCI-E Power Connection
 
I have a 7600 GT for my PCI E slot and didnt need a special power connector for it, just slide it in the slot and good to go.
 
Now I wanna upgrade to something like this 8800 GT but I am not sure I can, do I need a special power connection for it?

Thanks so much for all your help

ok simply will this card work? i have a pci e slot, but i dont know if i need a special power line for it or what.
 
anyone have a clue?

You need to have the 6 pin connector from you PSU to connect to this and many other higher-powered GPUs.  
 
If your PSU doesn't have one of these connectors, you're out of luck.  The power provided through the motherboard isn't enough to use one.  
 
You can get a pretty quality PSU with for a decent price if you look around and don't mind dealing with rebates.
 
Sorry man.  Good luck if you do want to get one and get a PSU too.

take a look in the case to see if you have one of these hanging around

 
if not, you could get something like this to get around that problem

 
it looks like it might actually come with one of those in the package:
 

 
is that the same type of thing there?
 
i did link my power supply and mobo, but when i look at the specs on newegg i cant seem to find anything concerning this, is there a way to tell from the specs there if i have 1 ?
 
 

yeah, looks like you should already have the adapter cable then. And I looked through the specs of your case/psu over at newegg but it didn't really tell that much about the psu connectors...
