Both of these options are around the same price, but could I go with something lower than a 7950 to max out all games? If not, then which option would be the better buy?

GTX 670 is better than 7950 boost edition in almost all games.its really a no brainer that you should get the 670.

PhysX is hardly utilized at all. I can only name a few games that make good use of it and only one or two of them don't support proper CPU physics. If you want it, then ok, but be sure that you have good reason to have it.

If you overclock, then the 7950 is generally a better option. If not, well, then it depends on how much you want to pay.

Can you link me to benchmarks of the 670 and the 7950 overclocked? It seems unbelievable that you can get a 7950 for much cheaper than a 670 if the former performs the same if you overclock it.

You can overclock the 670 too, although its not the usual overclocking business. You just set the offsets higher than normal.

Having said that - the 7950 can be overclocked quite a bit. Check out this article that Tom's wrote about the 7950. Overclocked to 1025mhz or more - the 7950 beat out the gtx 670 in crysis 2

I love those comparisons, if you overclock one super high and don't overclock the other one, then the 7950 is better!

I don't know, you could maybe, imagine the 670 overclocked? It will spank a 7950.

Like I said, you can overclock the gtx 670. Its not the exact same as overclocking other cards though because you only adjust the offset.

For example, you adjust the power target from 100% to 110% or gpu clock offset to +100mhz and memory clock offset to +150mhz (just picked some numbers).

After overclocking the gtx 670, it WILL outperform the 7950 OC.

Nope. 7950 can overclock by around 40-60% (sometimes more with particularly good cards, but I'll be reasonable about this and not go into unlikely extremes) and the 670 can't come near such increases by percentage. The good 7950d can make up the lost ground and gain some in an OC versus OC comparison.

7950 has more headroom than the 670. OC versus OC, 7950 generally wins:

That 670 is the best 670 (it's been discontinued, evidently it was a limited edition) and this is not the best 7950. I think that the 670's memory could have been pushed further, but it wouldn't have changed the winner, just closed the gap a little.

If you want to know why Nvidia prices their cards higher, well, overclocking isn't factored into prices and Nvidia often does it anyway. Look at the 680, performs almost exactly like the 670 despite being 25-340% more expensive and the 660 Ti and 660 are a similar example. It doesn't need to make sense, Nvidia just does it. AMD does some similar things too. For example, the 7950s with 7970 coolers overclock equally well, making most 7970s wastes of money.
