Hi All, I have been given an old server that has 6TB drives and a 240GB SSD, with 24GB DDR3 1600Mhz memory. The issue is the CPU. At the moment its running I5 2600 Skt 1155 CPU, i was looking at changing to I7 3770K. What are your thoughts on this legacy CPU? I have read some good things and some bad things about it. Bearing in mind that this is going to be a gaming rig, would you go for this processor? Any help CPU suggestions would be gratefully received. Cheers...
