Games running slow on good cpu/gpu

Games like new super mario bros and super mario galaxy 2 are claiming to be running at 100% speed, but are horribly slow. What confuses me is that I've seen youtube videos with nearly identical computer builds as mine run the games perfectly well.

Video Card: Radeon HD 4870
CPU: Intel Core 2 Duo e4700 @ 2.80GHz
OS: Windows 7 Ultimate 64 bit
RAM: 4 gigs

I've tried using all the default settings, both direct 3D9 and OpenGL. And messed around with settings such as disable fog and removing framelimit. The only thing that really helps, and brings it to basically perfect speed, is disabling EFB copy, which has its own set of graphical issues. I've read that you would only need to do this if you have a weak GPU, which I don't think is my case.

I've also tried giving dolphin highest priority in task manager, with no effect.

If anyone has any advice please offer it. Thank you.

Also, my harddrive is really full right now, with 44/640 gigs free, could this be causing any issues?

EDIT: I'm using the latest 64 bit windows revision posted on the website. Is it just a matter of the new revision being slow on some systems?

Have you tried EFB copy to texture?

I tried it before for super mario galaxy 2, and I saw no significant change. I just tried it on new super mario bros though, and that seems to have fixed all the slow down, seems to be running at near or at full speed for what I've seen so far.

Could you tell me why copy EFB to RAM is causing such huge slowdown?

shouldn't my computer specs be able to handle EFB to RAM?

You do have a dual core processor clocked @ 2.8ghz, but the processor itself is nothing spectacular.

Many of us here would use a Core 2 Duo E8000 series, like E8400 or my model the E8600.

Anyway, most of the time you will want to use EFB to Texture as it gives much better performance, at the expensive of minor graphical inaccuracies.
Some games like Mario Sunshine may require EFB to Ram, but other than that...

Depend on your gfx ram (512Mb atleast)and benmarks score,you can handle well
I don't use EFB to Ram btw.I set resolution 1366*768 (HD 720p) and Anti-Alias: 4x ,OpenGL resolution: 2x

Accuracy always comes at a cost of performance, copying external framebuffer reads/writes to ram with current PC hardware is a very expensive operation and tends to cause severe performance degradation with games that heavily rely on copying EFB reads/writes to ram in order to produce accurate effects.

With my Core2Duo E8500 @ 3.16 Ghz, 4 GB DDR2 Dual channel ram and 512 MB Geforce 9800 GT, my frame rate is halved in New Super Mario Bros. when using Copy EFB to Ram. With more powerful hardware, there may not be as much of an impact, but it will still be slower than hacky less accurate methods.

I think there is some other issues.
