Ok i made a big mistake bought a crossfire instead of sli... i was just gonna go with the 2900xt in a crossfire... but when asking what psu to buy for my system i was chewed out like a rubber ring for dogs... will the gtx perform on my 965P-DS3P or should i scrap my expensive mistake and list it on ebay 1/2 price and get an nforce or sli board?
 
You won't have any problems whatsoever running the card on the board. The motherboard supports crossfire, it doesn't require it.
 
Performance with a single card will be the same as with an SLI board, yes, but SLI obviously won't be an option in the future.
 
thats fine... im not sold on SLI anyways i think Crossfire is better but Geforce cards are better than radeon cards... makes no sense
 
Yeah , but if you are not in a hurry.

wait tell the next drivers wave from ATI , they say it will improve the card performance a lot.

The drivers will increase performance, but not enough to make it a GTS/GTX killer.

If you buy a 2900 you have to remember;
- It costs $100 more than the 8800 GTS
- It puts out more heat than the GTS/GTX
- It uses more power than the GTX
- It is noticeably louder than the 8800 series
- Has less performance than the 8800 GTS 320MB
- nVidia's drivers will improve over time too
- AA is broken with the card right now
- even if the 2900 matches the GTS/GTX in performance, it is still 7 months late
- ATI is going to release another card in 2-3 months with way better performance
 
The 965 chipset is a poor performer for any dual VC setup. The problem is that the second VC has to send all its data via the South Bridge chipset (like the ICH7 or ICH8 or something not Intel). This slows down all the communication to about x2 maximum (instead of x8 typical or x16 optimum).

I got the 8800GTX and I think it is the best card available on the planet. But if you like the 2900 specs, that's fine. But just remember that you will not be happy with any dual video card performance of either NVIDIA or ATI when using the DS3 motherboard because of the 965. In all other cases, the DS3 is super. I love mine! :D :D :D

I thought the second PCI-E slot was 4x :confused:

It is. It actually pulls PCI-e lanes from other sources when used for a VC. However, the post about having to send data through the SB is correct. The 965 chipset was never meant to support multi-card solutions, as it lacks peer-to-peer communications capability. The ability to do this is a driver workaround by ATi.
 
It's a driver workaround, but still, 4x PCI-E slot would severely limit most high-end video cards. Not worth trying it.
 
I did the same thing but I bought a SLI board instead, im just going to sell my 1950pro when some direct x10 games come out and buy and 8800 :)
