I bought my brother PC .....Asus rampage formula 4x2gb RAM from Crucial Q9550 with AC Freezer Xtreme and GPU GTX 760 Very,very good PC especially CPU is too much old and still powerfull and thanks to 12mb cachce [Sep '19 Antimat]

MORE DETAILS

The i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date. The many users that had the good sense to purchase this processor should feel in no hurry to upgrade as it's still no slouch, even by today's standards. The benchmark figures indicate that, even at stock clock rates, in terms of real-world performance this processor is approximately 20% slower than the best currently available, not bad considering its age. Given that the 2500K has an unlocked multiplier upping its performance by 10% with stock cooling should not pose much of a problem for the majority of owners. Here is a detailed performance comparison of the 2500K vs 4670K.  [Jul '13 CPUPro]
