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.
