Is it my processor or video card that is too slow

[zelda_fan]

I recently downloaded the latest stable version of the Dolphin.  

Although most gamecube games run slow and laggy in some levels. Especially when there is alot of detail.  

I'm trying to figure out what is affecting the speed.   So i plan to get a new video card or processor.


Here are my current specs for my computer:


Intel Core 2 Quad CPU Q8200 @ 2.33GHz 2.34GHz
8.00 GB Ram
Window 7 64bit
Nvidia Geforce GT 640 2GB
Dolphin: 4.0-9023

I'm thinking it's my processor that can't handle the emulator? Since it's only 2.33GHz 

Or is my video card also too old?

Can someone give me some advice?


I am planning on getting this processor in several months:


Intel Core i7-5820K Haswell-E 6-Core 3.3 GHz LGA 2011-v3 140W


It's a 3.3GHz compared to the 2.3GHz that i have now, would 3.3GHz be enough?


I really want a 6 core because i do a lot of multi-tasking, If 3.3 is not enough, this is my second option,

Intel Core i7-4790K Devil's Canyon Quad-Core 4.0 GHz


Although that one only has 4 cores, but it's got 4.0GHz, i know the emulator only uses 2 cores, but i want 6 cores for my personal work.




I really want to continue playing on my computer, it's very convenient.





Thanks!
