If I pop in my 5770 into my backup 3.71 e5400 then I can't max it out I have to disable VSync and HBAO to run it.
To be fair, i3s are much more efficient clock for clock as compared to athlons.

When you put your 5770 into the e5400 rig, I assume it is the cpu at 100% and gpu at less than 100%, correct?

Quad cores have always been better for gaming. Maybe a few years ago you could get away with it, but now it is more obvious than ever. So what if a lot of games aren't able to use more than two threads? Are you only running a game? The OS has to use those same cores as well. Why not spread the load?

yeah BFBC2 bottlenecks the 5770.

in Crysis/Metro 2033 i saw a huge increase in framerates when i replaced my core 2 duo with my core 2 quad.

bc2 also got a very healthy increase in frames as well. Dual's had their time, but it is now the era of the quad cores and so forth.

i had no qualms spending 200 dollars on my core 2 quad (last year) ...completely worth it.

I guess the majority of people in this thread didn't bother to read this article.
They disabled the cores of a 980x and tested multiple games including some new ones.
As you can obviously see, the difference between 2 cores and 4 in most games is non-existent and is at best marginal in others.
I would say it all has to do with architecture and speed for gaming, not cores.

However, if I were going to build a brand new system from scratch, I would probably go with a quad simply because the price difference isn't massive.
But if it money really is tight, I would go with a new dual core and a faster gpu.

If your building a new Rig now, then defiantly a Quad....

I get 90% CPU Usage in GTA4 with my E8400 (3.71ghz) and 100% GPU Usage...

I had a problem with drivers that made my GPU Usage go to 40% and not to anything and then onslaught of people with i7's Blatantly saying Get a Quad, buy this buy that, so I changed OS and Drivers and it was all good

Not in games that support more then 2 threads and especially not in systems with more then one GPU. Heck, a game that supports 6 native threads will run faster on the 6 Core Phenom.

Hyper threading is good, but's NO replacement for real logical cores

Faster per clock performance only gets you so far, That's the original reason why AMD and Intel started adding more cores instead of focusing on clock speed and per clock performance.

it depends, but the advantage of the core performance of the sandy bridge over the "k10.5" is huge, so in some games, even using more than 2 threads with some efficiency there is no warranty, but of course that in many cases were you optimize for more threads the difference in core count is to big, but most games will only use 2-3-4 cores with some efficiency and so...
take a look at FC2 a game that sees great advantage in more than 2 cores, but even so the dual core with half the l3 sandy bridge (i3 2100) beat the higher clocked Phenom II x4
the same in dragon age and many others

in many cases is just to hard to parallelize something efficiently, so its hard to replace the single thread performance,
