Opinioni personali:
secondo me ha senso solo la 7750, grazie ai consumi ridotti che non richiedono alimentazione ausiliaria. Per il resto, la 7770 deve ringraziare esclusivamente la frequenza del core elevata, perchè una 6850 portata a 850mhz prende il largo costando meno, e consumando poco in più...
La 7770 mi sembra una scheda molto tirata di fabbrica, e portata ad 1ghz di core sopratutto per fare scena.
A voi la parola ;)
