Hello.

I’m changing dedicated server and the new server have i7 3930K CPU. Is that one better for plex or worse than mine E3 1245v2? How many trancodings willit be able to handle?

PassMark - Intel Core i7-3930K @ 3.20GHz - Price performance comparison

Yes. Almost 3000 PassMark points higher
PassMark - Intel Xeon E3-1245 V2 @ 3.40GHz - Price performance comparison
How many trancodings will it be able to handle?
Depends on the quality of the stream:

The Guideline

Very roughly speaking, for a single full-transcode of a video, the following PassMark scores are a good guideline for a requirement:
◦1080p/10Mbps: 2000 PassMark
◦720p/4Mbps: 1500 PassMark

Thanks. I have read somewhere that the i7-3930K uses the GPU builtin to process with plex (or something like that) and that plex is performing poor with this. Is this correct?

Plex Media Server does not yet have this feature for Intel Quick Sync. It is being worked upstream:

But is the PassMark score depending on support for that?

No, that is pure CPU software encode.

◦1080p/10Mbps: 2000 PassMark = 6 streams roughly with the i7
◦720p/4Mbps: 1500 PassMark = 8 streams roughly with the i7

Thank you. This was very useful infomation.
