7900 GTX going to SLI ...

Just a quick couple of questions here as I will soon be adding another 7900 GTX to my system. The only issue I have is the existing card is an ASUS and runs at stock speeds while the new one is an XFX and is, as usual, over-clocked from the factory. So:

1. Will the video driver automatically throttle down the XFX to stock speeds so it will run OK with the stock ASUS card???

2. What issues might I run into trying to OC the cards (or at least OC'ing the ASUS to run at XFX speed) and what's the best program to OC SLIs - still Riva?


Since this is my first shot at a video OC I may need more help once I'm into it but for now I just want to make sure it'll be Plug-n-Play for the new XFX card. Thanks in advance for the help ...!

1) Yes it will run at the slowest card's speed.
2) As long as the slower card will run at the fasters speed, none. Riva = yes.

Good deal! Thanks for the quick reply ...
