So I'm looking to buy the 5830 for just Bitcoin mining and I'm just wondering who's the best manufacturer?
I see a lot of the 5830's in the marketplace are by Sapphire.
This is for single GPU mining by the way, I don't plan on running crossfire.

Well, I liked the xfx 5830 as it had double lifetime warranty and I forget if it had over voltage control or not.

I liked the sapphire xtreme 5830 as it had over voltage control but with only a certain warranty not sure wha it was.

In between the two, I found by xfx and sapphire from experience to be the best. Take your pick.

Oh, the fan on the xfx kept dieing and xfx kept sending off a new fan unit every 3 weeks upto 3 times. I ended up slapping a 120mm fan on the hs.

I had 12 of the sapphire 5830s at one point and I never had one fail in a year of mining.  I used up to 5 per machine using a 1000w PSU and the MSI GD-70 Mobo.  The key is keeping the heat down below 85c all the time.

any manufacturer usually works out fine IF it is using a reference board and coolers, otherwise sapphire is top for amd, xfx is newer to the amd side but has a nice warrenty for resell or modding ; H.I.S is good too

Sapphire's RMA process is a total joke.  It's awful.

I don't know about this - my sapphire cards usually come back from rma in 3 weeks or less.
