Compatibility problems with Asus P5KC ???

[fretman]

I asked a store to put together a system for me and just to give me the parts and details and then I would research it a little further. Here's what he came up for me.

Intel Core 2 Quad Q6600 2.4GHz 8MB/1066FSB S775 CPU, Retail
Asus P5KC iP35 S775 ATX Mainboard w/Audio/GB/DDR2&DDR3/eSATA/FW
OCZ Vista-Upgrade 4GB DC PC2-6400 DDR2 Memory Kit
Seagate 7200.10 500GB 7200RPM 16MB SATAII Hard Drive, 5Yr
LG GSA-H62N 18X DVD+/-RW SATA Drive BLACK, OEM
BFG Geforce 8800GTS OC2 320MB PCI-E Video Card
Antec SonataIII Mid-Tower Case w/500W PS, Black
Microsoft Windows Vista Ultimate Edition DVD (64Bit - OEM)

My question is this. I told him that I wanted Nvidia graphics so he gave me an Nvidia graphics card. However, when I did a little research on the MOBO it seems that the MOBO supports Crossfire technology.

Correct me if I'm mistaken but isn't crossfire technology supported only with ATI graphics cards?

Does this mean that I cannot put 2 Nvidia cards on my system because of that MOBO?

If yes, then I would have to point this out to the person who put this system configuration together for me and see what he has to say.

Thanks.

You are correct, you can't use SLI on a crossfire board, or vice versa. You can put 2 Nvidia cards in, but only to drive multiple mionitors, SLI wouldn't be supported.

So if down the road I wanted to put 2 nvidia cards then my MOBO needs to be replaced I guess.

However, since the system hasn't been put together yet what MOBO would you recommend if I wanted to take advantage of SLI.

I would prefer to stick with the P35 chipset though. I'm not sure if P35 supports SLI.

P35 does not support SLI, some support Crossfire though

On the other hand I don't reccomend SLI or crossfire. A next generation card will beat two last generation cards in SLI or crossfire. Plus heat and compatibility issues. I think you are almost always better to buy a new card and sell your old one.

You would need to go with a 680i for SLI.

Good point. I'll stick with one video card. Thanks.
