I want to buy a new 27" iMac for normal web browsing, music streaming, photo editing and World of Warcraft. I've read that World of Warcraft is quite CPU dependent, so would the i7 ( 3,3 vs. 4,0 GHz ) be the better choice? Should I choose the m395 or the m395x to play with good framerates? Unfortunately, I couldn't find any benchmarks with this exact configurations to compare if it's worth the extra cost. What do you all mean? i5 / i7 and m395 / m395x?
