i cant decide between a opteron 175 and a x2 4800. i know opterons can be overclocked but x2 4800 are said to be extremely good. and on benchmarks perform extremely well, however cant find the tests were opterons are displayed. Which one do you recommend? which could be overclocked to a faster speed without going over kill on the overclock? Which will be better in GAMING which is mostly importatnt to me thanks!
