CF, are you kiddin?
Your asking for advice?
Your testing us aren't you!
I dont have the actual review but I think its a safer bet to get the 1800. Its the 1900 + that have trouble ocing i "think" (quit laughing).
Ti4200? My o my your coming up in the world. What happened to not needing that excessive hw. Now I'll have to get another card too.
ps:sorry bout the chip etc, frying is the one thing that makes ocing interesting.
