Hello, can a sapphire hd 7850 overclocked to match the performance of 2 hd 6870 in crossfire
More about6870 7850
I'm not going to look for benchmarks and stuff, but from my gut instinct I'm going to say no. Heat would be an issue.
yes but it will generate more heat and if u use aftermarket cooler for the card it might block ur airflow and both will not be running at x16 not reccomended might as well change to a single powerful card
2 6870 > 7850, assuming the 6870's do not run out of ram
