well i found few topics on web, where was said that:
1. e6600 3ghz 2mb cache is bottlenecked by 650 ti
2. e7300 is bottlenecked by 460 se
so when I check toms hierarchy chart, 460se is 2 level lower than 650 ti, and I assume it really looks, that gtx 650 ti is maximum i can utilize on my system.
well its already ordered and incoming, and 7850 would not be much of help to me as I already purchased separatly far cry 3 insane edition and 7850 comes with far cry 3 while 650 ti comes with AC III
I should get the package on tuesday so we will see how much gpu will be used in bf3, since skyrim is cpu intenso to use it as benchmark.
