Which is better?

[MatthewEnderle]

I have dual 7970s from XFX and the Ghz editions. I also have a Nvidea Quadro k5000 in my truck. I'm not really interested in the amount of money made, but I just want my computer warmer to use as a heater. lol

What is this for? Mining coins? Folding?

dual 7970s... but make sure they don't go over like 85 or it'll be harmful to them

For a heater, all of them. For gaming dual 7970s

You can probably get a cheap 480 off ebay, it's one of the best space heaters available.

Reference single slot HD 4850 is a better heater. =p

Mining will generate more heat than folding and more heat than most synthetic benchmarks.

 

I wouldn't recommend mining on the XFX 7970 GHZ cards. They will likely die sooner than other cards. The cooler design places a heatpipe extremely close to a capacitor. For normal use this causes no issue, but the heat from mining can cook and cause the capacitor to pop. They are also voltage locked and can have a difficult time getting past 550 K/hash.
