Way to create a straw man by debunking what I never said... Different GPU architectures aren't created equally. 'Feel' is a subjective term, at worse 460@850MHz is around 30% slower than a stock 7850 and at best its within 10%, depends on the game. If an OC'd 460 is running a game acceptably it won't feel much slower than a 7850.A stock 460 is approx a stock 6850. And no matter how much you oc it, it can't match a 7850. Period. That is like a 50-70% performance diff for which oc isn't enuf. The diff may even be more. It is like saying a 560 ti 448 oced matches a 670. No. It doesn't.
A 460 at 850MHz performs roughly on a par with a 470:
A 460 at 850Mhz would be roughly 5-10% slower than a 560 Ti, 560 Ti against an OC 7850@920MHz:
470, 560 Ti and 7850:
The OP never said he can max FC3, so yeah, all of what you said in relation to the OP is BS.My 7970 at 16x10 can't play fc3 at max no AA and that is equivalent to a 460 tri sli or faster in terms of real world experience. So all this is bs.
