This conversation is doing circles all the time.
"Bulldozer sucks"
"Why, it is fast enough in some things!!"
Well, fast enough doesn't get you anywhere, you need the whole package. And no, bulldozer is not "fast enough" when it fails to keep steady >60fps in Guild wars 2, Borderlands 2, Starcraft II to name a few games.
Your comparison also doesn't make any sense. Your i7 came out in 2009? Now if the successor to your i7, had worst performance in many cases and drained watts like a dog everyone would also say it sucks, which is what happens to Bulldozer compared to Phenom / SB,IB.
Also, it's a bad overall choice. Noone 7zips all day long, and the best choice is almost always the all-around better one.Bulldozer is very good in some special and rare cases,and mediocre to modern realistic workloads.
The fact that Bulldozer is "fast enough" holds no value when i5 is even faster, consumes half the power, overclocks better, and is better all-around performer. 0 out of 4 reasons to prefer BD.
