Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I am planning to use one to clean my computers. Are they safe? I have one that has small tank attached to it. Slighly bigger size then a vaccum cleaner but is 20kg+.
The chart you provided did not provide results for GTX295 or even GTX260 SLi
Look here instead:

[If you look at ALL the games and compare, it shows that GTX295 is generally faster then 4870x2.]
