Is it compatible and/or worth the extra money?

[dafydd_brown]

I've got a Gigabyte GA-K8NSPRO mobo ( http://tw.giga-byte.com/Motherboard/Products/Products_GA-K8NS Pro.htm ) and am looking to buy a new graphics card. Now this mobo has a NVIDIA nForce3 chipset and so I'm assuming that ATI cards are out of the question. Also I'm slightly confused as to whether my PCI slots can handle a PCI-E card and if it's worth using an AGP card in my AGP slot.

Having read a few posts on the issue of graphics cards and such I was wondering which, if either of these cards would be better and if they will be compatible with the mobo I've mentioned?

This first one is the cheaper and is a GEFORCE 6600 PCI-E 128MB TV+DVI *Extreme Gamers Edition*' [/B]

and this second one is an 'Evesham GeForce 6800 128MB DDR AGP' but is OEM and so I don't know if I'll be missing anything important because of that...

Is it worth spending the extra for the 6800? and does the whole PCI in a PCI-e slot or AGP in a AGP slot make any difference to the issue?
Thanks for any insights... I know this is not a particularly new topic!

just so you know i have a nvidia mobo and it works fine with ATI.
ATI and nvidia chipsets ARE compatible.

P.S: go with the ATI Radeon X800 it kicks the 6800 in the ass.

As for PCI-E, your mobo manufacturer should be able to tell you whether or not it supports it. But, in all likelyhood, probably not.

no you dont have pci-e, and yes an AGP port on any mobo can use ATI or nvidia. pci-e will require a special mobo, and you will know if you have it or not, it is quite new and a little expensive for now. however the general consensus on this forum is to go for the 6800GT from EVGA, that 6600 you cant use because you dont have pci-e and the other 6800 is prolly not the best bang for your buck.

as for OEM, that prolly means it wont come with any driver CD's, cables, warranty information, or anything else.
