what the title states, i already ordered Phenom2 X3 720 2,8Ghz black edition for which amounts to 130 dollars including shipping, but i just found a Phenom2 X4 945 3,0Ghz black edition that i can get shipped for free for 140 dollars. should i take the 945 instead? i have only gaming in mind.
I've never seen a 945 black edition before, thought the only 3.0Ghz black edition was the 940, you might want to double check that because the 940 can only be used on AM2+ boards with DDR2 memory.
I wouldn't even consider the Phenom II X2, it'll win in a number of games due to higher clock speed, but a vast majority of new games show benefit to having more than 2 cores and in new games the X3 can pull ahead.
