I ahve one AMD Radeon 6950 with an Asus DirectCII cooler... However that's triple slot, and when I go crossfire, I want to know; how well will two 3-slot cards side by side stay cooled? I'm looking at these cards for the secondary:
Another point - the MSI is clocked at 850/5200, wheras the ASUS is at 810/5000... If the Asus is at the bottom, the back fan is directly above the bottom fan of my case, whereas the front one is above the PSU. I have a HAF 922. I also have a side fan which blows onto the cards... So would it be viable to clock the ASUS to the MSI clocks? Or would I not notice any difference anyway?
You can get any card you want and then OC it, and i would go with the MSI ones the Asus Direct CU II will take a lot of space and bottleneck your move.
The sapphire Toxic has a HD 6970 factory BIOS and it performs better than HD 6970 but they will run hotter and noisy.
So sapphire Dirt 3 or Twin Frozer II is my recommendation both are great.
Another thing, what's the hell with the prices ? $460 ??????????????
This is remembering I already have one 6950, teh ASUS one?
Only thing I'm worried about is temps. I have a 200mm fan blowing right on the sides of the cards though. So should two of the Direct CUII ones be fine? I just don't want them to get ridiculously hot, as the rest of my system says quite cool.
