i7 920 @ 4ghz - still good?
How do they compare in games today against what on the market?
Reason i ask is because i'm offered one for free to replace my 1090T, wondering which would yield the best performance (frames). (280x gpu)

If you can get it for free, together with MBO, take it. Otherwise, keep your Phenom.
You can see here that they perform more or less the same.
1090T is better than I7-920. Overclock as much as you can without raising voltage more than 1 step. Use DDR3-1600 low latency. 7-8-7-22 1T. Overclock the IMC as much as stability will allow.
Phenom II X6 should last for another few years especially if Mantle takes off.
I'm running an i7 920. With hyperthreading disabled, I get 4.0 with stock voltage (and that benchmarks games better than the 3.6 with hyperthreading enabled).
Be aware, when OCing, even without voltage gains, the TDP goes way up.
That being said, it still runs games just fine; however, when compared to a 1090T, the gains would be modest to say the least outside of synthetic memory benchmarks.
Intel-specific stuff would do better, HT minimizes the core advantage the 1090 has, both overclock well - so aside from a few games that just run better on Intel architecture, you'd be hard pressed to really notice a difference.
Only reason I said 1090T is better is because of the 6 cores and it is slightly more future proof. In general you will not notice the difference between the 2 unless an app is heavily threaded. But even then very little difference between the 2.
I'm just theorizing that with Mantle the 1100T will outperform the I7-920 by a bit.
As far as I'm aware, AMD hasn't released the full details of exactly what Mantle is. But it certainly isn't a way to magically make all past AMD hardware perform better. It's not clear if it's relevant to CPUs at all (and even if it is, it would probably be only of the APU variety), and if AMD isn't even supporting it on Radeon HD 5000 and 6000 series cards, it's very unlikely that they'd support it on long-discontinued Phenom II chips.

No that is because the Phenom II x6 has 6 cores vs Intel's 4. Mantle will utilize all cores and multithread the graphics. So the x6 would be a stronger processor with Mantle. Perhaps even matching the 4770K if the X6 is OC to 4ghz.
On the CPU front Mantle will have only special signifigance to Kaveri. Otherwise AMD and Intel Processors will both get a performance boost when using GCN GPU's
Mantle dosent care what CPU you have.

Well, the i7 is 4 core with HT - those HT cores aren't 100% efficient, only ~40% efficient - this is true, but it still shows up as a full 8 core CPU to software. But 8 Cores with 4 only 40% ... all other things equal that's pretty darn equal to 6 full cores, give or take depending on the nature of the work load.
That isn't quite right. HT only uses spare cpu cycles. So if 1 core was at 60% then the HT thread would only have 40%
1 thread at 80% would leave HT at 20%. Cache thrashing can also impede HT performance since there is only 4 blocks of cache per 8 threads.
HT is just an additional worker thread per core. it does no work in itself. Helps for multithreading sometimes. Usually very little gain.
What i'm trying to achieve is higher minimal frames with less micro stutter along with increasing the overall frames/performance i get in eyefinity.
I have a feeling that my 1090T is dragging things down abit (main factor is probably the am2+ board its attached too..) and am hoping that a a 920 clocked the same as a stock 1090t (3.3ghz) will beat it clock for clock revealing a 20-30% increase in frames.
Im pretty happy with my 280x its quite beasty from what i previously ha, but im looking at getting another one in time to push better performance in eyefinity with crossfire.
So my my main concern i get from this thread is overlcoking...i have a 650cx corsair psu and wondering if it will blow with an overlclocked 920 + 280x? (and later another 280x.)
its a complete system, and its free its simply a question of which will yeild the more performance.

Yes, but it also takes advantage of out-of-order execution. This gives you more than you are giving it credit for.

In the synthetic benchmark with perfect core scaling, you see a decent increase by enabling HT and effectivly doubling the core count. It's not a 100% speed boost, like perfect scaling would indicate, but about 30-40%.
In gaming, the results are more dramatic. In the Core i3 (a dual core CPU with HT), the dual core results are often abysmal and enabling HT is nearly a 100% gain in some games. In the Core i7 (a quad core with HT), and some games on the i3 where cores past 2 can't really do anything anyway, you see virtually no difference, or even a slight decrease in performance, as you lose some efficiency with the overhead from the higher core count.
With regard to the microstuttering and such - maybe, it's worth trying if it's free (and you don't have OS issues from swapping the motherboard), but I wouldn't bet on it fixing anything.
For the power supply: a 650 is fine for what you got, even with moderate overclocks (I wouldn't crank the voltage up very far on that 920 though while OCing the video card). I wouldn't run CFX on it though, especially with overclocks.
I was thinking of upgrading my 920@4k but after reading this anandtech CPU test. I saw no reason to spend money on CPU + MOBO and got myself new R9 290 instead

That is an excellent article.
It is indeed. Thanks Aren! I think I am going to link to it every time I will see someone say "bottleneck".
