Opera hardware acceleration despite not enabled by default works very good on most recent systems, it can make use of crossfiresli configurations.
And i have to say, its damn faster with it enabled.
I use opera because its safer and because of its usabilty, recently i found an independet review made in december,testing browsers anti phishing security , and opera scored 94%, the second was ie with only 82%, and chrome (webkit), just 72%!!!
Changing to webkit will mean less security… right?
i will use the last opera (PResto) version available for as long as i can…
Ps. Surfing on YOutube and buffering 1080p videos, since version 12.13,its like flying.
That does not happen with IE and Chrome, Firefox 19 its a bit better but not better than in Opera ( I have to say i like the smoothness of this firefox version!).
But i have to agree with compabilities with websites, the last two versions started to crash sometimes on websites that i frequently use..
Rip Opera.
