Another Phenom II X6 1090T owner here. Mine is overclocked to 4.07GHz and paired with 16GB of DDR3-1740. It's not my main computer, but the performance is fine enough that it easily could be. 😀
As far as single-threaded performance goes, it's slightly faster (5% tops) than my Q6700 @ 4GHz. It just leaves that C2Q in the dust in multi-threaded stuff.
My only concern (and this applies to the 65nm Core2 as well) is the lack of true SSE4 support. Yes, the PhII has SSE4A, but are there any programs out there that actually use 4A? All of the SSE4-optimized apps/games I've seen only use Intel SSE4 (45nm Core 2 and newer). On the AMD side, you'd have to "upgrade" to an FX chip.
I have a hunch that HEVC decoding/encoding takes advantage of SSE4. I have a 4K, 60fps, 10-bit HEVC video file that I use to measure a CPU's software-only HEVC decode performance. The 1090T @ 4GHz simply cannot do it. All six cores get completely slammed. It handles 4k/60 H.264 wonderfully, but HEVC kills it. My Core i7-4930K plays that HEVC file just fine, and with very low CPU usage (~25%).
