Sapphire Radeon HD7970 GHz Edition 6GB Vapor-X Edition VS EVGA GeForce GTX 680 Classified 4GB

Hardware Hub GPU

Just a quick Question regarding these two GPU's. Which in your opinion is the better of the two.

7970, Nvidia removed a lot of the compute power from their cuda cores so Nvidia ends up limiting itself for what it can do. If you notice in the majority of the games that aren't optimized for Nvidia cards AMD wins out. Look at the benchmark chart for the 680 titan that has been swinging around. You'll notice the 7970 ghz beats the 680 even on Nvidia's benchmarks. Not to mention the fact that 7970's overclock a hell of a lot better than 680's. Oh and it's cheaper.

7970 is better but I wouldn't buy the 6GB version unless you're doing multi-monitors.

yreah, 6 gigs of vram is overkill unless your doing a triple 1440p eyefinity

I don't have experience with 3x 1440p monitors, but I can assure that even 3Gb is more than enough for multimonitors. Unless you are getting several thousand dollars worth of screen hardware (or $1000 worth of Korean 1440p monitors), having more than 3GB of VRAM is useless. 2GB is not enough for multiple monitors at higher resolutions, but 3GB, 4GB, or 6GB (7970 6GB or Titan), will work just fine. The more pixels require more umph to calculate the colors with precision. I recommend the 7970 3GB, or 7970 3GB 2-way Crossfire. You will have much more power from 2 or more 7970s than from a single 6GB 7970, and be able to drive higher resolutions just as fine. I bought a 4GB EVGA GTX 680 FTW+ because when I got it, the benchmarks were in favor of it, and it wasn't much more than a 7970 3GB. Now, the 7970 seems to be on par with 670. The 670 and 680 have a smaller memory bus width, which means that they can't use as much memory effectively. The 7970 has a 382(?) bit memory bus width, which is 1.5 times as large as the 600 series 256-bit memory bus width. The Titan also has a 382-bit memory bus width, but has more computational power inside. A single Titan, however, isn't much or any better than 2x 7970s, which can be had for several hundred less. However, 2x Titans are going to murder everything, including 3x Titans, which is probably due to scaling or SLI issues. I would get 2x 7950s or 7970s instead of a single 680 or 6GB 7970. However, both cards individually will still be fantastic.

do you? shut up, and stop being an asshole.

Thanks for the info. I'll look into getting the 3gb version :)
