770 = 680, they are the same card, just rebranded. You are essentially getting a 770 for 85 bucks less. I would go for it, however you will need a new power supply, assuming it is going into the system in your sig
A new 680 is as new as a new 770, because they are the same card, the only difference is that the stock clocks of the 770 are higher than the stock clocks of the 680. You essentially have a factory overclocked 680, not a whole new card. It is the same as the 8800GT vs 9800GT or 9800GTX+ vs GTS250, they are identical cards.
i now its the same card, but for a little more money a faster 1 without a overclock.
that you have to overclock the 680 to get the results from a 770.
and if you dont want to overclock, and have the money extra buy the 770.
overclocking is still, more heat, and more heat means higher temps.
dont get me wrong i love to overclock, but if you dont whant that i mean.

So I ended up not going for the GTX 680, I won an auction on a new GTX 670 for $232. I'm satisfied.
If you're still using that VP450W PSU you will need to upgrade it for the GTX670. The VP450 can provide (Max) 360W on the 12V rail which is insufficient for a card that can easily draw 200W when overclocked and a CPU that has a TDP of 70W.
It should work, but a very bad idea. Do not overclock anything with that PSU at the very least.
