Crossfire Radeon 7850

post #1 of 3
Thread Starter 
I am planning to sell my Radeon 6870 and buy two Radeon 7850s, but I'm unsure which ones to get. I've heard the reference cards exhaust heat out the back and custom cooled ones don't. I have some questions: Is the card reference (http://www.pccasegear.com/index.php?main_page=product_info&cPath=193_1373&products_id=19820), and would it oc well and work well in crossfire, or would this one (http://www.pccasegear.com/index.php?main_page=product_info&cPath=193_1373&products_id=19799) be better.
Thanks!

I would get the Sapphire ones, with the copper heatpipes and dual fans the cards will run cooler and quieter with a lower fan speed, also they provide better cooling for the other components on the card, vrm, mem chips. They are both dual slot cards and in crossfire I would think the Sapphire's would have an advantage with more cooling area and more surface area for the fans to collect cooler air, as long as you have adequate exhaust in the case you should be fine with the better coolers that recycle the air.

Still though I would just get a Sapphire 7970 o.c. as I did today, I really think its best to get the single best card you can and when you need more then add another card, why go through the trouble of crossfire/sli when some games utilize it for the better or worse and drivers, micro stutter, power consumption adding to the negatives as well?.

Only reason is that the 7970 is about $150 more expensive in Aus.
