Will a 5400rpm caviar green be sufficient for gaming?

So I've thrown together a gaming PC and ordered all of the parts, and realized I made a really stupid mistake.
I ordered a 5400 rpm HDD instead of a 7200 RPM HDD.
The hard drive in question is a Western Digital Caviar Green 500gb HDD.
It IS cheap, but it has good reviews.
Now, I was wondering - I'm currently using a 3 year old 500gb Seagate Barracuda 7200 RPM HDD, and I've heard all over just how terrible Seagate hard drives are.

Will there be any framerate loss in games with a 5400 rpm hdd ?
I understand that loading will take longer, but if I'm going to end up with tons of stuttering and crap it's going to be unacceptable.

You wont get any in game effects, all of the data is offloaded to the RAM when it loads, you will however get a significant difference in boot and load times compared to a good 7200RPM drive.

I rarely turn my PC off, but I don't mind long boot times.
Load times are also fine, as I mostly play MMOS where the world is streamed.
This is the one thing that worries me the most though.

How would games with streaming worlds run? Something like GTA4 or Champions Online?

Thanks
