Aloha, would anybody be kind enough to give me the overclocking "low down?" Is overclocking a graphics card under the right temprature conditions; 1, reletaivly safe? (ie, no blowing up, or dying instantly) 2, worth the hassle? 3, gaining a noticeble amount of preformace? Im new to GPU overclocking, and my aging 8800gts 640mb could do with a boost. would the £20 thermalright cooler be worth the preformance gains?? gunna check out benchmarks now, but if anyone could help, it would be much apreciated.
