E8500 @ 3.9mhz is Great. Spend $300.00 for a quad you cant predict will oc as much? For gaming, a quad is good for a few games. Look at what you play and compare with the published benchmarks. I predict you'll spend $300.00 for little to no gain.
thanks IntelEnthusiast - do the extra cores in i5 / i7 help the game performance indirectly by taking the overhead (processes) from the OS? Otherwise, i'm assuming the game would have to be coded as a multi-threaded application to see the advantage - true?
Right now very few games can take advantage of more than 3 threads. Because of the value of the hyper-threading and extra cores of other processors is largely useless. So a game like World of Warcraft can take advantage of up to 3 threads and will give you an advantage up to that point. Just a quick look for information on the games that have listed doesnt show much multi-threaded support but newer games are coming out support it all the time. In the next couple years I would shocked if most major titles release didnt have some multi-threaded support.

Yeah, I recall reading an Anandtech article about multi-core performance improvements... If I remember correctly for the few games that can use all 4 cores, the average perform increase from dual core to tri core was about 26%. The jump from tri core to quad core was on average 6%.
