Title: 5770 + 6770, good idea? Post by: crazy987 on July 20, 2011, 11:36:12 AM I want to expand my current computer which is riggerd with a MSI Radeon HD5770 1GB PCI-E.
I was thinking about the Sapphire Radeon HD6770 1GB Vapor-X. So i then have a crossfire setup for gaming, and 2 VGA's for mining with +/- 350mhash. However, its been a while since i read about CF. But will this work or will it give conflicts since its a completely new serie? Title: Re: 5770 + 6770, good idea?

2 6000 series cards perfrom worse for bitcoin mining than 5000 series cards in general. you're better off getting a 5830 or better, you'll get 300+mhash from that card alone Title: Re: 5770 + 6770, good idea?

Plus i cant get a 5830 new, only second hand and im only buying new stuff, never second hand Title: Re: 5770 + 6770, good idea? Post by: deslok on July 20, 2011, 10:40:40 PM on that note then depending on prices i'd lean more towards a 69xx card instead of a 6770. unfortunatly you're not going to be able to run mixed generations like that in crossfire, i'm going to refer you to amd's own chart

Post by: smoki on July 21, 2011, 02:33:39 AM 6770 cards are just re-labeled 5770s, apart for some minor bios differences. So yes, you can Crossfire them, as the chart linked by deslok also confirms.
