Thanks guys for your inputs & efforts.
I was browsing through threads & came across "Best CPUs for money - in India" reference thread. BD is not included at all there & a friend of mine is serious in the combo of FX-8150 + GA-990FXA-UD5 ( still in the process of shortlisting a game card ).
He is a linux enthusiast with requirement of virtualization like me ( it's our job ) but also wants a good rig for gaming.
He even referenced a this URL for me.
PassMark - AMD FX-8150 Eight-Core - Price performance comparison
Could I get your feedback on this since BD comes nowhere in the list of the mentioned CPUs.
Thanks..
yup, that thread is written by me. But it is written from purely a gamer's perspective, that's why I didn't include FX-8120/50 there. (I think I'll update it now FX-8120 should get a slot for workstations)
But in your case (and may be his case), I can see VM applications being benefited by AVX, XOP and FMA4 instruction sets (supported by Bulldozer, not Phenom II) in the future. But lack of VT-d in i5-2500k is bad. i5-2500 has it, but then you can't overclock it. One doesn't really get Intel as the choice.
Now, in games FX-8120/50 were not performing consistently. Minimum FPS used to drop. Only today a patch by Microsoft was released to improve its thread scheduling in Windows 7 which improved performance in games (99% don't use more than 2 or 4 threads). Earlier 4 threads were being run on cores 0,1,2,3 and now they run on 0,2,4,6 (alternative cores) which has made performance in many games smooth. Like I said, it'd get better with time.
He can go with FX-8120/50 if he wants. FX-8120 is more worth it actually.
