I just ordered a KuFormula VF1-PLUS for my 6800GT AGP, does anybody know how much of an OC I can get with this? With the stock cooler I can only get about 400mhz/1.4g without getting artifacts. I live in Miami so its hot here and I need something to cool my Video card really well. I have read some reviews from Toms and other sites but I just wanted to know what some of you think of this cooler. Thanks.
