How screwed am I? (liquid damage)

Well, long story short, my computer I built (with an Antec DF-85 case), managed to get water damage. A little liquid managed to get through the top part of the case, through the fan, and into the system while it was running. Needless to say, the computer immediately shut off. It was a miniscule amount, but apparently it was enough. When i opened the case, there was a small moisture spot on the top of my NVIDIA 570 GPU. I looked over the motherboard and saw no moisture on it at all (unless it evaporated already). My build is as

-NVIDIA 570 gpu
-Intel I5 2500k
-Asrock Z68 Extreme3 Generation3 motherboard
-Corsair 850w psu
-8GB Corsair DDR3 RAM

Basically, is there any hope that anything isn't fried, or should I start looking to immediately replace my components? Somebody I talked to, who has about 30-40 years of experience in computers said that he's seen something like this twice, and both times the CPU was ok. Anybody else have experience with this, and can tell me what to expect?

Cpu should be fine, if its only on the gpu then i dont see why anything should be wrong, the only thing i can think is that it got on to the mobo

If it turns out that water did get on the Mobo, what should I expect there? Obviously a new Mobo and possibly a new 570. Would the RAM be done as well?

I spilled half a Rockstar in my Antec 902's big boys mouth once.
He was thirsty !
Rig shutdown and within a ms i turn off the psu power button.
Removed the ram and gpu and cleaned the rest up.(mobo)
Had it up and running in about 2hrs.
Been fine ever since,i'm using it for this post.
I have 7 fans running in the case and i guess that helped out alot.
To this day, whenever i clean it, i still find reminders of the mishap.
Rockstar Mocha is sticky and i find little droplets in unbelievable places.
My case now resides on a side table instead of the floor.

Boot without the GPU and see if you at least POST. If you do, then the mobo is *probably* stable. But its sounding like the GPU is basically done...

I once had half a can of coke spill into a computer from the top. I spent 3 hours cleaning it out with a q-tip and alcohol. After giving it about 72 hours to dry out, it booted up just fine and ran for over 3 years before I had to replace the video card.

The majority of the system may be salvagable, but it sounds like your GPU is FUBAR.
