For fairly old architecture it's great. Big bang for little bucks!

Summary: Got this for a PC that I was building for my wife for her Christmas present, to get her off of an ancient HP Pavillion 1.3GHZ system. She seems very pleased with this. I haven't been too impressed with benchmarks I've seen online with this processor when compared to my 9750 which is only .2GHZ faster, but it still performs very well. This was purchased NIB for about $61 including shipping, so who can complain about that, for a quad core that runs decent?
Highly recommend if you are a gamer, or encode videos.

Summary: Just upgraded from an AMD Athlon 64 X2 2.9 GHZ Brisbane. There is NO comparison to the speed of this Phenom. I have it overclocked to 2.51 stable running at 79 degrees with a 15 dollar Coolermaster Heatsink. I know some people say this CPU runs hot, but I can't get it to run over 85 degrees, period. It is fast, sleek and scores high on the Windows Experience Index. At 2.5 GHZ I scored a 6.9. Not bad for a mid range AMD Quad! If you want a cheap upgrade, here ya go.
Summary: I've used this chip on a number different builds. The performance for gaming with a single mid-range GPU is complementary, with no bottle neck. It encodes video at an efficient rate and multitasks nicely. The Phenom 9550 is actually faster in the 64-bit versions of Windows 7 than in 32-bit operating systems. This means that benchmarks for the chip that were used when it was first released are not accurate.
Summary: I have built my PCs with AMDs since 1998...with the exception of the OVERPRICED i7s, the AMD chips will out perform those Intel chips...don't get caught up in the Intel advertising...try an AMD and you will be amazed with the performance and cost!...I'm an AMD CPU fan for life!...
