The Intel machine will be faster (with our without overclocking considered).
Remember it has a "turbo" feature, increasing the core frequency to some 3.4Ghz.
PCSX2 runs faster on Intels architecture anyway.
well youre mother borad may not support intel then you have to buy a new one ( and even the amd one might dont work eighther because the cpu might not supported) and if you dont overloock it the temp well be fine but
yes i'm gonna buy new motherboard for sure, but i'm confuse first about cpu witch i chose intel oe amd .. then i will buy a good motherboard for it.
Checked his motherboard (MSI K9N Neo V2) and it looks like it doesn't support AM3 processors. Whichever way he goes, he's going to have to buy a new mobo.
Based on the FFX-2 benchmark, Lynnfield/Bloomfield is roughly 20% faster clock for clock comapared to the Phenom II. Performance-wise, the i5-760 running at 2.8GHz with Turbo Boost disabled will be roughly equivalent to a Phenom II running at 3.4GHz. With Turbo Boost enabled (and CPU affinity set to maximize Turbo), the i5-760 will clock at around 3.2~3.3GHz and you'll need 3.8GHz on the Phenom II to match.
Turbo Boost is kinda like overclocking except it does so in a way so as not to exceed the processor's thermal and power specifications. If you're not overclocking, though, I suggest waiting for Sandy Bridge (Q1'11). It seems to have a more aggressive Turbo compared to current Nehalem processors. Right now isn't really the best time to build a new PC.
