hi, I am hoping someone here can help me. I recently purchased a MSI HD 7950 and I overclocked it to 1020/1575 and I am still getting very poor performance. Running Witcher 2 on below high settings it is still stuttering and hitching on me. Where as I read that with an OC 7950 it would run ULTRA flawlessly yet I can't even run High well. Also when I ran the Kmark test..about 5 times I would get x1767 which is about the same score people are getting on a gtx570. I'm not sure what I could be doing wrong, any help or advice would be appreciated. I am running 12.11 CAP2. intel I-5 3750k 3.4 8g of Ram MSI radeon HD 7950 OC twin frozer 750watt Corsair TX Win 8 Thank you.
