BadTrip :
Can you read? I mean seriously can you read? Where in this thread did anyone say anything about Intel dual cores. Phenom I was crap and everyone knows it. Everytime you post such stupidity, you lose even more crediabilty. Stop, read, research, think, then post something sensible.
Phenom I was not "crap", though with all the misinformation out there... many people may "know" it was crap.
The first iteration was bugged, and was indeed "crap". You don't want to buy a 9x00 chip. However, the 9x50 series was actually a very serviceable chip, and competed fairly well in high resolution gaming compared to the Intel Quads at the time due to their high bandwidth. This was not shown in many common benchmarks, which focused on low res gaming (at levels nobody played at)... but check the high res benchmarks from that time and you'll see why Intel found it important to move to the integrated memory controller.
I ran my 9850 Black Edition at 3.2 to 3.4 Ghz. It was cheap, and a strong performer. I bought the Phenom II 940 as soon as it came out, and was able to push it up to 3.6 Ghz with relative ease. The performance difference between the two at equal speeds? Around 5 to 10% on pretty much every benchmark, which is somewhat minor. But the difference in public perception was (and is) relatively large.
That said, the 9x50 chips are good bargains right now, and you can build a pretty solid gaming system for cheap with them. It's a little less attractive with DDR2-800 memory becoming more expensive... but it's still good bang for the buck.
