- Do any games not run at more than playable frames with a decently clocked phenom and a decent GPU? nope.

The point is besides benchmarking there really isn't that large of a difference in performance in GAMING, which is what we spend this money for (well most of us). if you're buying the latest stuff to brag about how much faster it is than what others are using then you are doing it wrong.

So to answer OP's question.
Will a phenom bottleneck a 560Ti? yes (mostly in benchmarking)
Will you notice it playing your games? NO.

this thread is pretty sad.

Ok Damric, I went and made it offical.

Do you have any actual games so we can get a better idea of what this all translates to in real world gaming?

Just toss me a few with built in benchmarks that you own, I'll be more than happy to help.

Now that you've made it 'official', are you ever gonna think of using them gpu's for ....maybe GAMING??? Just thought id ask!

Here is a basic run, its pretty cpu intensive though so I'm pretty sure you should stay clear of it.

AMD Phenom II X4 955 vs Intel Core 2 Extreme QX9770

That being said, the i5 750 is about the same as a Q9550 @3.2 Ghz, and even loses in 3 out of 4 games.

Intel Core 2 Extreme QX9770 vs Intel Core i5-750

If you move up a bit, to the Core i7 950, it wins a lots of tests, but it still loses against a Q9550 @ 3.2Ghz in 3 out of 4 games.

Intel Core 2 Extreme QX770 vs Core i7-950

It's only when you move to the 2500k that you can see a clear win in games (it even wins against the i7 965).

Intel Core 2 Extreme QX770 vs Core i5-2500K

So, as a conclusion, the Phenom II is at the bottom of the list for a new aquisition if you want to play games, and the first Core i5/7 Intel lineup doesn't fare that well either against the Core 2 Quad (a Q9550 at 3.2Ghz ties in games with a Core i7 965), so the choice is 2nd generation Core (2500k/2600k).
Those three games you're harping about, Fallout 3, I'd actually consider a 5-way tie. The difference in Crysis Warhead is more pronounced, but the results are clumped close together so there's clearly still a GPU bottleneck. Left 4 Dead shows a bigger difference but that's because the framerates are so high. I'd consider this one a 4-way tie between Deneb, Yorkfield and Nehalem with Sandy Bridge having a very slight lead.

Fallout 3
X4 955: 86
QX9770: 87
i5-750: 86
i7-950: 85.6
i5-2500K: 90.3

Left 4 Dead
X4 955: 121
QX9770: 133.3
i5-750: 130
i7-950: 124.9
i5-2500K: 142.7

Crysis Warhead
X4 955: 81
QX9770: 86.9
i5-750: 83
i7-950: 86.1
i5-2500K: 91.6

For a single GPU solution, Phenom II is fine. Heck, even for CF/SLI, assuming you're gaming at 2560x1600 (or higher) at high settings, there are few games which the Phenom II will bottleneck. Alas, unlike Nehalem and Sandy Bridge, there doesn't appear to be much room for upgrading the GPU on the Phenom II before it starts to become an actual bottleneck.

Average is kinda meaningless, at least to me.

Avg min fps (and how often the lows occur) is what really matters, I wish more review sites would take note.

You forgot it's not three games, it's four. The fourth is Far Cry 2, and the Phenom loses miserably. I hope it's just a coincidence you left that result out.

its like buying a bulldozer chip, Oc'ing it to 5 Gigahertz and going onto a core2quad forum and asking users with a chip that can barely crack 4Ghz to compare their results.

With a single mid-range card you should be fine on that CPU at those clocks.
You most consider the bold because the GTX 560 Ti have overcurrent protection, just as the GTX 580, it seems like most non-referens don´t have though, so if you have a referens card you might have to lower your OC to see if your score get better.

Checkout this article, Geforce GTX 56o Ti Power Consumption Protection Analysis


If you´re bottlenecked?, not much in real game, probably some more in benchmarks but what´s most important for you?

No it's not. You're making a comparison that doesn't make any sense.

What I compared was the Phenom II to the Core 2 Quad, both of which top out at the same overclock - at around 4 Ghz, like you said.

And then to make it clear in the gaming department I even added a few other CPU's, like the i5 750, i7 950 and finally the i5 2500k. The result is that in gaming the Core 2 Quad is better than a similar clocked Phenom II; the i5/i7 from the first generation don't improve this by much, if at all (although they can generally overclock a little better - not worth changing platform though), and the i5 2500k shows appreciable gains, even at stock.

Now what does that have to do with what you just said ?
