And also what about the features? Does it really do anything or they are just trying to make it sound better.

Example:
sapphire 7970 features:
AMD Stream Technology

AMD Avivo HD (DVD/HD-DVD/Blu-ray Playback)

AMD HD3D Technology

AMD Eyefinity 2.0

AMD App Acceleration

AMD PowerPlay with ZeroCore Power Technology

AMD HD Media Accelerator

AMD PowerTune technology (with Boost)

Gigabyte features:
"Triangle Cool" Technology

Gold plated HDMI

OC GURU ll

AMD Eyefinity

AMD EyeSpee

Avivo HD

Just recently I got my first Sapphire card and I was surprised about the quality of the card and the packaging. The card even came with a HDMI cable.

Faulty graphics cards usually break down within days, weeks or months. If it's still running after 2 years there's not much to worry about.

overclocking is based on silicon lottery. but generally sapphire cards overclock well. if you want to aim for 1200+ mhz the voltage control is an advantage.

also there are 2 gigabyte cards . the Gigabyte HD 7970 OC(1 ghz) for USD 400 and Gigabyte HD 7970 Ghz(1.1 ghz) for USD 450. both cards are voltage locked. if you choose gigabyte i would advice you to go with USD 400 card as its easier to overclock to 1100 mhz on most HD 7970 OC cards. few cards overclock to 1200 mhz at stock voltage but generally its not so easy to hit 1200 mhz without voltage control. so the extra 50 bucks on the ghz card might not be worth it..

They're trying to make it sound better tongue.gif . Also OC GURU ll Utility is garbage, can't control memory, core voltage, can't go above 1100/1575 (for original 7950). So you must use MSI Afterburner or Sapphire Trixx for overclocking AMD cards. OC Guru is no different than AMDs own Overdrive, it is only good for wasting hard disk space.

I might just go with the sapphire and oc to 1200mhz is that good?
post #46 of 50
My friend and I each recently bought a Diamond 7970 reference card. Both overclocked to 1150mhz on stock volts, and up to 1200mhz at 1.2v and 1250mhz at 1.24v.

I got my vram from 1375mhz to 1575mhz with no voltage change, and my friend got his up to 1600mhz.

The stock heatsink is decent, but insanely loud. We were able to oc both cards to these settings on the stock cooler, core temps around 70-75C with the fans around 60-70% (Loud as hell). VRMs at stock were running around 60C, and about 80C after the OC.

I ended up going watercooling, mostly for the noise levels. The temps are a lot better (about a 25-30c drop on both core and vrms), and I might push the voltage a little higher for some benchmarks.

My friend ended up buying an aftermarket accelero cooler. The VRM temps didn't change, but the core temps dropped by about 20c and it runs a lot quieter as well.

Tests were done in about 23-24c ambient room temp.

+rep for making a wise choice. It's the only choice I'd make in this crowded field of compromised offerings.
