Are the NON Leading edition. So then there is the 7970 vs 670 in uncooked overall performance. So, 7970 crossfire users and 670 SLI users alike, i would love to listen to from you. There are a few factors you should think about here. The Asus DirectCUII is an amazing cooler, and incredibly quiet even following overclocking. Whilst you are searching at a 670, I believe the 7970 also comes with this type of cooler. You are correct that the 7970's are the kings of overclocking, but the main thing to think about for this SLI is how numerous monitors you are operating at what resolution. The 7970's arrive with 3GB of memory, extremely important when contemplating resolutions over 1200, and when you want to strap on MSAA, TXAA, AA, Supersampling, and high res textures. These are going to eat absent at your VRAM, and while have two 670's with 2GB each, does not mean you will get 4GB total memory, as VRAM doesnt stack in SLI, each card just uses its own memory to shop the data for the frames its processing. The GTX 670's are monster playing cards, and I would usually choose 1 of these for 1080p gaming regardless of becoming an AMD consumer myself, but for the price, the quantity of VRAM and the general overall performance, I'd roll with the 7970's for crossfire on numerous screens at higher resolution. Nevertheless, one thing to think about, is the frame latency on the 7950's and 7970's, which is a miniscule amount greater than the GTX 670's and 680's, which have a reduce body latency. Most people dont notice, but for avid enthusiasts, they may notice a couple of fractions of a millisecond delay in body processing. I'm really not new right here, my previous username was "Enmity" but when these darn hackers hit TPU I misplaced the ability to log in. So I emailed Wizz to get it sorted, he stated the Servers had been just being bombarded so just wait around for the "forgot password" e-mail to arrive. It never arrived and I have just been busy. Presently only running a Samsung XL2370 keep track of (1920x1080) but my subsequent purchace is going to be a 27ish" 2560x1600 monitorregarding the DCII's yeah the 7970 arrives in a DCII taste too, but sadly these things are three slots, rendering my soundcard useless due to slot configuration. There are a couple of elements you ought to consider right here. The Asus DirectCUII is an awesome cooler, and incredibly peaceful even following overclocking.
