Fallout 3 & New Vegas

Dead Space 1&2
Dead Island
Battlefield 3
Battlefield Bad Company 2
Aliens vs Predator
Metro 2033
Warhammer 40K: Dawn of War II
Dead Rising
I mean, these are just games from my Steam list... all of those made full use of the Xeon I had back when. wink.gif
Personally, I would go for the slower quad core, because games will prefer a quad over a dual core.

http://www.anandtech.com/bench/Product/120?vs=85

3.2ghz dual vs. 2.6ghz quad. This is only a 24% clockspeed advantage in favor of the dual-core, compared to a 36% clockspeed advantage of a 3ghz dual-core over a 2.2ghz quad-core.

I took the liberty of highlighting games that appear in the Anand bench. Contrary to your theory, the bolded games are faster, on the faster dual-core! Now, I will take your word that they use quad-cores. However, those games won't equally split the load on all 4 cores. There are probably minor tasks that get offloaded to idle cores.

Perhaps the best evidence is a typical i3 dual-core compared to a Phenom II quad-core. This is pretty well documented, take a 3.2ghz Phenom II 955, compare it to an i3-2100 for gaming and multi-threaded performance. The results are always, AMD quad faster for multi-threaded, and the i3 is faster in most games, even "ones that use quad-cores".

One more example, since you mention most games use a quad-core with HT (meaning 8 logical cores). Since AMD FX-8150 has higher multi-threaded performance than the i5-2500k, wouldn't that mean Bulldozer = better for gaming? (NO, this is not BD flamebait, don't even think about turning it into something).

It still stands that a dual-core with a 45% faster clockspeed than a triple-core, will have approximately the same multi-threaded performance. So, fast dual-core = better gaming performance on games that can only use 2 cores. At worst, it's the same gaming performance as a triple-core, although as I've explained, I still think the dual would be faster in multi-threaded games.
