I think you might have missed something. I'm not asking what card to buy - I already know I want a GTX 460. I'm trying to decide when to buy it and if I could save a decent amount in a couple months.
sorry, I just figured that since there are two memory configurations and multiple factory oc models available that we could help you if we had more info. for example, I just got a gtx 460 768mb card for 146 shipped NR. This card is excellent up to 1680x1050 in most games, but quickly dies off after that due to limited bandwidth. some games even at 1680x1050 might be better with the 1gb card or one of the oc variants, however, while some games you'll be ok even at 1920x1080 with 768mb card depending upon whether you want to OC or not.
I don't think that you'll see much better msrp than ~$150 for a long time, and even deals better than that are likely to be few and far between even if 6xxx kicks the snot out of fermi. However, in the 1gb cards I haven't seen anything below $200, and the future price of that card depends upon where 6770 and 68x0 performance goes, where amd decides to price those cards, where 5850 price drops as a result, and how much stock amd actually has left of 5850 at that time.
So the questions that I asked are still valid and can help us help you. If you don't want the help then no problem.
