Are waterblocks worth it? - Page 2

GK110 has a lot of OC headroom, so in this case going with water cooling would allow you do do things like flashing a custom BIOS and really upping the voltage. In theory, you could probably go from around 1100 on air to 1300 on water, depending on how hard you are willing to push your chip. Going with a Classy would be very beneficial in this situation, the chips are capable of 1400+ on the core but on air they tend to reach their thermal limitations before their silicon ones.

I have only one thing to say. When you go water, there is no coming back. smile.gif

So in my case, watercooling doesn't really let me OC any higher, as I reach my chips's natural/silicon limitations before I reach its thermal ones.

exactly this. I started w/c my GPU and never looked back after the first one. Then I got a card where I got almost better OC's with the stock cooler than I did with it on water. Still, it was worth it to me to start w/c my GPU's. It always gave me a nice performance bump. Plus, I always had a better CPU then GPU so that helped
