now should be somewhat similiar to your case, although you might need to factor that there might be some diference in performance between i3 and i5 (except core number, since it doesn' matter in dolphin)

mario galaxy 2 => tested on mario "face" ship area. playing around, riding yoshi, eating plant.
got 52-55 FPS, when things get wacky, and lots of effect/action, dip around 47-48

mario kart wii
tested single player on liugi's circuit
smooth 60 FPS, sometime few drop in FPS, but still in normal range (2-3 fps drop)

when tested on 2 player split screen (since no one arround, 2nd player only stood there on starting line)
FPS varied beteen 45-55. on some occasion i can get smooth 60FPS

all using DSP LLE and mostly default dolphin 3.0 setting (no setting tweak for performance)

so, i3 2120 is adequate. might need some tweaking here and there if you want to use LLE

Wow thanks for the fast reply. Seems like a stock i3 2120 isnt enough to get constant 60 FPS.

My last request: Can you test the 2 games (same settings) with 3,5 Ghz, 3,7 Ghz and 4 GHz on your 2500K? This way we can see how well the Sandy Bridge CPU scales with Dolphin and it would help out alot of ppl on which CPU to get, if they are on a tight budget like me Smile

Thanks in advance setya5785
well, without LLE DSP and some performance tweaking (disable audio throttle and/or other graphic setting) i think it is possible Smile
you could also try older revision (most people said r6505 is the fastest) or optimised build using SSE4.1/4.2 or AVX

i3m though without turbo boost (and 4 bin OC advantage other sandy bridge non-K series had)

btw, @3.5GHz using same testing (default + DSP LLE) and same level to test
mario galaxy 2 => smooth 60 fps, on some occasion, when there's alot of action/effect, dip to arround 52-55 FPS

mario kart wii 2 player split. most of th time 56 - smooth 60 FPS, depend on how many other racer on screen. sometimes can get below that when there's explosion or other flashy effect

i didn't test 3.7 and 4 GHz, but i think its result kinda obvious

or if you have any extra cash, might as well invest on the less expensive i5 sandy bridge, the i5 2400 (about $40 cheaper than 2500K, and $40-$50 above i3 2120).
all i5/i5 non K series do have turbo boost and limited overclock up to 4 bin ratio

i5 2400, stock 3.1 - > TB 3.4 GHz
add 4 bin OC -> TB 3.8 Ghz (single core active) and 3.5GHz when all core active
pump up those base clock up to 105 MHz (max safe increase for SB BCLK), you can get up to 3.99GHz turbo boost when single core is active (or 3.7/3.8 when all core active)

some info

but, it's better to get K series if you have OC in mind

p.s : i'm not recommending to upgrade and/or overclock just for the sake of emulation.
@setya5785

Thanks again for the infos I really appreciate it: I will buy a 2500K. I need the cpu power for video encoding anyway, might as well go for a cpu that can handle the dolphin emu.
your welcome.
don't forget to get aftermarket cooler if you're planning on overclocking Wink
