Ah, here we are with yet another (dare we hope) interesting
article from a line of tests measuring performance scaling of one of
the most successful cards in the low-mid gaming segment this year -
AMD HD 4770 512MB GDDR5. Today were going to measure a two cards
against three in CrossFireX mode. But that's not all we're even going
to use in our tests two of the most popular gaming processors - Intel
Core i7 920 and AMD Phenom II 955 Black Edition.
