2 row vs 3 row Radiator efficiently?

Recently bought a 2 row 28x15x2 cheapo alum radiator. Anyone have direct experience with replacing a 2-row radiator of the exact same size with a 3-row?

I'm using 2 12" electric fans. This has cooled the car fine up until I use the AC in stop and go traffic on hot days. Without the AC on the car will stay around 190-210* (180 thermo). Even on 100*+ days I've seen a highest reading of 210 or so. On the highway I can run the AC on hot days without any overheating issues.

Due to engine packaging and turbo plumbing, I have no room for a schroud. The radiator is covered decently by 2 12" fans. I know a schroud is best, but I just don't have the room.

Do you think switching to a 3 row core radiator will make that much of a difference? The 3 core units I'm looking at are the same 2" thickness as my current 2 core. I just can't see them cooling that much better?

I'm also looking into a more powerful fan setup. As these are the supplied cheap fans.

-Thanks!
