Hence why I'm on the fence... and may just wait for a 4GB 670.
It's important to remember that you generally have about 15-20% of 'overhead' when it comes to memory usage before you start suffering a perf hit from 'running out'. So a 670 isn't going to 'run out' in a tangibly negative way until the usage is around 2.3-2.4GB ...
I guarantee you that it's not 'worth waiting' for a 4GB 670 if you're planning on running one card. It might be if you want to go SLI, and run a massive resolution though.
If anyone wants to feel better about getting a 2GB card, check out the SLI 680 vs XFire 7970 review over at [H]
. They run every test at 5720x1200, and the GTX680 comes out on top in terms of max playable settings on every test except BF3 Single Player (680 tops out higher in multi-player believe it or not).
The biggest question in regards to performance and gameplay experience about GeForce GTX 680 SLI was if the 2GB of VRAM per GPU and lesser memory bandwidth compared to Radeon HD 7970 would be a hindrance. Our testing has clearly answered that question. In fact, in every game we tested, GTX 680 SLI offered a better gameplay experience compared to Radeon HD 7970 CrossFireX. We specifically tested at NV Surround and Eyefinity at the maximum resolution of our configuration at 5760x1200 to see if there would be any bottlenecks. We found that the new GeForce GTX 680 SLI has the performance where it counts.
This is a bit of a generalization though and doesn't mean that 680 is 'always faster' ... cause it's not, especially not compared with both cards overclocked
There are a few games out there that are heavily memory-bandwidth sensitive like original Crysis and Metro where the 7970 is the clearly superior card to the Kepler offerings.
Frankly at the current price of $449, if you're an OC'er ... the 7970 is a monster card. At that price I have to say it's a better choice than the 680 at $500. It becomes a little more arguable compared to the 670 at $400 though.Edited by brettjv - 5/17/12 at 10:41am
