Im not sure how to spend my cash 
If im running a 570GTX SOC would it be more well spent if i went the route of a custom watercooled case or adding another for SLI?
I have a Corsair 600t SE white and if i do not custom loop, an antec cpu water cooler but the rest of the case would be on air cooling.
Whats the thoughts?
