what's wrong with AMD? D;
The fact is the strongest CPU they have available is 6 cores and it still doesn't compare to the quad cores of the i5 i showed you, plus AMD's are less futureproof
A pentium 4 lasted a few years for me, AMD's need updating every 2 years time.
i5 2500k is probably your best, if you ever want to speed it up the overclocking is possibile, make sure you have a good cooling though
All my main PCs have used Intel, i've used 3 Godly PCs in my life - Back in the day of pentium 3 & 4 was the good days
