9800 GT Green Edition worth it?

I just bought a PALIT 9800 GT 512mb GREEN Edition, its a powersaving edition,http://www.palit.biz/main/vgapro.php?id=1210

But I really wanted a 9800 GT and its performance, I'm kinda worried sick that Green edition is a lot weaker than the standard 9800 GT, is it really so much weaker that I might have wasted my money?

Considering that you could've gotten a XFX 9800 GT for $5 more that had free S&H, yeah...

Palit's Speeds
Core Clock - 550MHz
Shader Clock - 1375MHz
Memory Clock - 1800MHz

XFX's Speeds
Core Clock - 600MHz
Shader Clock - 1500MHz
Memory Clock - 1800MHz

The cards already downclock themselves when not in use to conserve energy.

Or you could've gotten a Galaxy 9800 GT at the same speeds as the XFX card and it came with a $25 MIR.
