Cinebench R11.5

The performance of the FX-4100 wasn't awful, but we didn't expect to see the AMD A6-3650 running at 2.6GHz to beat the AMD FX-4100 running at 3.6GHz in benchmarks like POV-Ray and Cinebench!

At 4ghz under water, the C3 revision of this chip is a very good performer for the price.

if u still got min budget n cant buy intel based rig. u r good 2 go with AMD FX 6300 chip which has AVX n AES instructons n if u r budget permits opt for an FX 8350 which will b good for the long run of the rig.
it's really true that phenom black edition cpu's(Solid gaming chip) still rock when compared to the newer quad core FX series chips there is not much performance jump between these two chips and the phenom 2 X4 single core performance and overall cores performance is 10% faster than the current FX 4100 chip. Even after 2.5 years there is still no performance improvement in the FX chips. what amd has done except for switching from 45nm to 32nm & instead of improving the architecture & efficiency they just upped their level 2,level 3 caches by 2mb and processing speed of 3.4Ghz to 3.6 n 3.8Ghz in the FX 4300. if u r in to just gaming n low on budget go for amd platform like this cpu AMD FX 4300@.3.8Ghz.ASUS.gigabyte based AMD 760G chip n a AMD 7770 gpu.with RAM capacity depending on u r budget. if u r in to productivity and wanna use u r pc for some photo n video editing n some threaded apps u can go for H61 based mobo from ASUS,gigabyte with Core i3 3220@3.3Ghz and a nice Gpu like HD 7770 or GTX 650,660.
