Hey, I am gonna try to liquid cool my cpu and gpu, but I don't know how much rad surface area I would need. in my case i can fit a 280mm rad and 1 120mm. will this be enough to cool my card and cpu? also I will probably be upgrading to sli 670s in may.

If you can afford that amount of rad in your loop, then do it.
To answer your question the general rule of thumb is 120mm per heat source, so 120mm for the cpu and 120mm for each gpu.
I like to double this value and utilize quiet fans for my loops.

For reference, I'm cooling a GTX690 and an i5-3570K off a 3x120mm radiator and 3x800RPM fans. No overheating issues. 1x120mm per heat source is an excellent guideline to go by.

The GTX670 and 3570k are both pretty cool running chips. I think that you would be more than fine with a 280 and 120.

I couldn't get away with just one space per heat source with three overclocked 7950s but those bastards run hot when playing with the core voltage.
