Hmm, so when they're running oc'd, they're pretty much the same speed as a normal 460 Sonic
Platinum (that card is 800MHz native). From specs I gather the EVGA is normally 763, and the
PNY normally 765. That puts them right in the middle of the range of default 460 speeds.
I know the Platinum oc's very well without the need for a different cooler, so it may be
you're going to be limited not so much by the cooler as the rest of the board (is it a reference
design?). A better cooler might not give you the extra oc headroom you're expecting.

Note that if one card has better cooling and the other not, you'll be limited by the least
capable card.
I used a Gelid Icy Vision Rev 2 to test the oc potential of a whole range of 460s back in
March. Results varied widely; seems like some cards are just already near their peak
performance, while others have a lot more headroom (bizarrely, one of the best cards I
have is a boring Palit 460 768MB 675MHz, but it oc's without a sweat to 868MHz).
Sometimes two cards of the same model will behave very differently aswell, eg. I have
an EVGA 460 V2 which happily runs at 1025 core @ 1037mV, whereas another one of
the same model won't go past 975 and needs a lot more voltage to get there (1062mV).
Trying a 3rd card achieved a slightly better balance, but still unable to reach 1025MHz
core with both:

Overall though, what's your end goal with this? From all the tests I've done, TBH I'd have
to say just getting a single newer card with more RAM is a better idea if you can, eg. a 670,
or a 7870/7970. Since I've been using my two main EVGA GTX 460 FTW cards for lots of
benchmarking (the ones that run 850MHz native), I decided on a different approach for the
time being, replaced them with two 900MHz EVGA GTX 560Ti 1GB cards (total cost 177 UKP,
uber bargain as they both came fitted with Gelid Icy Vision Rev 2 coolers), which together
run very well at stock speed (faster than a 670):

while oc'd they easily beat a standard 680:

And it frees up the FTW 460s for benching. The games I'm playing aren't affected by the 1GB
RAM limit, so that's not an issue for the moment (odd thing, Crysis2 with the settings I use will
grab 1370MB if the VRAM is available - tested with a 2GB 460 - but it runs fine with my 1GB
cards, don't know why). What games are you playing? Is VRAM capacity a factor for you? I'm
just thinking in terms of how much you'd end up spending on better coolers and long term
power consumption, perhaps that would be better spent on a single newer/better card (baring
in mind the sale value of your existing cards), whether used or 2nd-hand.
