Ok here is what my computer has on it ATM...
-Processor-AMD Athlon 64 processor 3500+ -->2.20GHz, 2000MHz FSB,
512KB L2 Cache
-Hard Drive-200GB ATA Hard Drive
-Memory-1024MB DDR SDRAM Dual Channel
-8 in 1-Digital Media Card Reader (Don't ask cuz I dont know )
-Video/Graphics Card-GeFORCE MX 4000, 128MBDDR, VGA + S-Video Out,
Core Clcok: 275MHz, RAMDACs: Dual 350MHz, Triangles/Sec: 31 million
4 pixels per clock rendering engine, 2 dual-rendering pipelines

Okay thats all the crap my comp has... From what I know I have a gangster processor and Hard Drive... However Im not sure about the Memory and Graphics Card... Tell me would this run Dolphin pretty well? And if not.. What should I upgrade? And if I do upgrade something what should it be to? Also take into consideration that if I do need to upgrade my Graphics Card here is what I think it will be... Tell me if this new card will be good

Radeon ATI 9550 256MB AGP Video Card
-8x AGP
-256MB DDR
-4 parallel pixel pipelines
-2 programmable vertex shader pipelines
-128-bit dual-channel DDR memory interface
-AGP8x/4x
-Dual integrated display controllers
-Dual integrated 10 bit per channel 400 MHz DACs
-Integrated 165 MHz TMDS transmitter (DVI 1.0 / HDMI compliant and HDCP ready)
-Integrated TV Output support up to 1024x768 resolution
-Windows Logo Program compliant
-ATI CATALYST Software Suite

I'm pretty knowledgeable about computer except GFX cards but from what I can tell... that new one is pretty good... If my GeFORCE 4000 doesnt run Dolphin at a good speed will that?

a 9550 is hardly a good card :S
you'll need something above 9800 Pro... and that wont even run full speed...

Radeon 9550 is for the museum. It is a VERY old grafic card. And no, you will not get better speed, i have a Athlon X2 4400+ DUAL CORE 2.2GHZ 1 GB RAM DDR 400 and a Geforce 7900 gt 256 mb(7900 gt is one of the best grafics cards right now,) and i get only 10 fps in Wind waker with dolphin

Best... hardly... what elements define what makes a good graphics card? I know mb is one and I'm getting a 512mb card to be more precise here is the info on it
Product detail - Radeon® X1600 PRO 512MB AGP

Wrong, MB doesn't define anything other than the amount of ram to store mainly textures on.

With midrange cards like the X600 series of both nVidia and ATi you are better off having 256mb on a 256bit bus, than 512mb on a 128bit bus. The same goes for 256mb of DDR3 vs 512mb of DDR2. Giving crappy cards 512mb is the best marketing trick to let uninformed customers buy these cards.

Getting a Cube or Wii will be the best solution if you want to play gamecube games before you can't even find them in shops anymore at all.
