Straight away we can see the performance improvement on offer from the Palit JetStream GTX 680 4GB when compared to the reference card. The problem is with the way Dynamic Overclocking works is the card performing faster because of the better cooler that Palit are offering, or is the 4GB of GDDR5 helping push FPS further?
In the end, for most, it's not really going to matter. NVIDIA deciding to release the GTX 680 with only 2GB of GDDR5 instead of 4GB seemed like a bit of a miss step from a psychological stand point. Most people feel these days that 2GB just isn't enough for high resolution gaming.
At the same time, though, NVIDIA by offering the card as a 2GB one were able to keep the price down and make it extremely aggressive. Of course there's always the option for partners to release a 4GB model as well and really that's exactly what we've seen here today.
This is a good model for Palit. Not only are they quick to offer us a 4GB variant of the new GTX 680, but they've also done with the new JetStream series which did a good job of impressing us when it came to the 2GB model.
I would've loved to have seen them overclock this model like they did the 2GB one, but as always there's nothing stopping you from doing that yourself via Afterburner. You'd probably find yourself going even higher than what the 2GB card is clocked at.
If you're not that interested in 4GB of GDDR5 you can get yourself the pre-overclocked 2GB JetStream model from Palit. If you found yourself thinking, though, that you'd loved to have a custom GTX 680 like the JetStream, but would really prefer a 4GB version, then what we've got here today could be the perfect video card for you.
