Xeon E3 1230 or FX-8350?

Solution
Where are you buying from? The FX 8320 is a much better option, ideal setup provided the case you have in mind will fit:

is faster and quieter, but outputs a bit more heat (not a problem if you have a normal ambient temp) than

I wouldn't really worry about which is better, but rather what do you need, as to not turn this into a fanboy war.





All the best!

The way you put this is just bad for everyone. If you're rendering the FX 8350 can easily match an i7 4770, which is essentially the Xeon 1230 if not closer to Xeon 1231. In games, the difference isn't 50%.

To answer OP's question, impossible to answer.

Yep, I removed my previous comment because the price : performance between the FX 8320 and i7 4770 doesn't apply here. I just assumed that the Xeon 1230 is priced similarly, which it isn't, which I realised the second I posted it. Regardless, if we take away the cooler for the FX 8320 and get a 212 Evo and only a slight overclock, the FX is way better value than Xeon. A lot of older benchmarks are misleading because there was a Microsoft patch which as far as I'm concerned, should apply to newer OS', but don't with older. But none the less, the different isn't 50% in FPS in games, that's ridiculous.
 


show me a single example of how a 8350 (without a extreme oc because not all the chips can get that high) will preform equivalent to a i7 4770. and the 1230 is almost exactly 50% faster in single core performance which will translate to fps in certain games with certain hardware.
 
I run a backup system with a overclocked fx 8350 running at 4.7ghz and intel smokes it in gaming.

Single threaded performance is miles ahead in intel which equals much better performance in gaming with intel.

arma is a good example of the need for single threaded performance
 


youre comparing $250 worth of amd processor & board against your intel system where the board & cpu alone cost $700+ ??

hardly a fair comparison in my eyes.


 
to go to the original question - yes the 1230 is better -certainyl not 50 % better though, its also considerably more expensive & I can't see you getting a used one for even close to the same money as an 8350.

the 1230 ,1245 & 1280 - absolutely no,I wouldnt buy into anything now on the old 1155 socket unless it was incredibly cheap & came with a high end board with sata 3 & usb3 minimum
I am assuming here that looking at second hand these are the v1/v2 cpu's that are socket 1155??
its going to be confusing as these chips have different generations that spread across all 3 intel sockets!

for gaming ,look at an haswell i5 if youre buying second hand ,plain & simple.
both intel k series chips & fx chips are too open to abuse from past users imo.
 


well yes it is but it was only for example, even the i5 4460 smokes it thoroughly in many titles wanting that higher single threaded performance
 


hmmm - 4 or 5 titles maybe in all fairness - & theyre either arma based or world of tanks/warships.

seriosly though,the op said irregardless of price which is kind of ridicolous - price is always an issue even if people say it isnt,otherwise we would all be running your setup but with a 980ti instead of that 970,& amd would be dead & buried.
AMD have the price advantage & really although i admit to being amd biased that really is all they have ,it always has & always will keep them in the game though.
