I'm wondering at what point does an overclocked phenom ii x4 match the performance of an i5 2500k at stock speeds?

Right now, i have my phenom ii 955 clocked at 3.8 ghz.

u can compare by itself use benchmark software or use SiSoft Sandra Lite

According to Various benchmarks, your looking at a 40 - 50% performance difference clock for clock on single core operations.

As a Result your Phenom II X4 would have to be 4.8 - 5ghz to be equal to the Sandy bridge CPU @ Stock - these are synthetic benches and calculations though.
An Educated estimate based on various benchmarks.

This isn't a direct comparative, it depends on software used.

You can try and match it to an i5-2400
i5-2400 (3.1) vs 980 (3.7)

Tada!

You still lose because Sandy Bridge's architecture is still too good! I also have 955, we also lose to the i3-2100... Dual core. :)  Intel is too good. Hence why i3-2100 is on Tomshardware's best gaming cpu list. It's really close to the i3-2100 but the i3 is SO much more efficient than an OC'd Phenom II beacuse it uses SO much less power.

i3 vs 980 (3.7ghz)
