Sapphire Radeon HD 7970 OC or EVGA Geforce 770 acx superclocked?

WC101 · Jul 3, 2013

I am building a gaming computer and can’t choose between the Sapphire Radeon HD 7970 OC or the EVGA Geforce 770 acx superclocked. This is my first time building a computer, so the only knowledge I have is from the internet. This is my list as of now.

• I5-4760k processor
• ASRock's Z87 Extreme6 motherboard
• SAPPHIRE Radeon HD 7970 OC or
EVGA Geforce 770 acx superclocked
• G.SKILL Ripjaws X Series 8GB DDR3 1600 memory
• Western Digital Caviar Black 1 TB data hard drive
• Rosewill Blackhawk mid tower case
• Corsair HX750 PSU
• SAMSUNG 840 Pro Series 2.5" 128GB SSD

My budget is $1300 but do not want it that high if unless I need to. I will be running games such as Star Craft 2, Minecraft, and Guild Wars 2 (as well as some others) on one monitor (ultra-settings on 1080p monitor) with another monitor for non-gaming use. I will be experimenting with minor overclocking in the future. Any recommendations with other components would be appreciated as well. (I already have a DVD R/W that I can use, and will be upgrading to a Blu ray later)

The Nvidia card would be slightly better in this case due to its superior clock speeds, the sapphire does have more vram but that can be made up for with clock speeds. It will run SC2 at ultra easily, I'm doing that with an old 7750 2gb ddr3 model. Just one change you your build though, I strongly recommend getting an aftermarket cpu cooler for the rig. Stock coolers are not the best and tend to be loud. The hyper 212 evo is one of the best air coolers.

You don't need such a high end GPU for what you're doing.

Gam3r01 :

Clock speed means basically nothing in this case, you're comparing two completely different architectures.

They may be different but having a higher clock speed is relavent, it allows the 770 with its 2 gb ddr5 to be on par, or even better than the sapphire with 3gb ddr5. Simply increasing the clock speed on my card added a 10-15 fps boost. Clock speeds are important in buying a gpu. The memory clock speed is also 4x faster on the 770. Side by side reviews of these two models also but the Nvidia about 8-12% higher than the 7970.

First of all, Tom's did a review and they're basically on par, and secondly, I'm talking about comparing two completely different architectures using solely clock speeds, which you seem to be doing.

If I put a clock speed of 2 GHz on a 620, it's not going to be faster than a 770, even though it has about double the clock speed.

Secondly, the memory clock speed isn't 4x higher. It's ~1750 on the 770 vs 1500 on the 7970, which isn't even a quarter. Yet (OMG OMG!) despite the lower memory clock speed, the 7970 has MORE MEMORY BANDWIDTH! OOH! WITCHCRAFT! Clock speeds don't say everything.

On a side note, would I say that an FX-4300 is better than an i7-3930k because it's clocked higher? No, the architecture is completely different.

You can't take these things as gospel but this comparison is leaning toward the GTX 770.

I'd prob go for that one.

Future Mark has got the 770 slightly ahead as well.

I think you are missing what Im getting at here, with these two specific cards, with these two specific manufactures the 770 is still better overall. The memory and bandwidth on the 7970 arent going to make it a better buy than the 770. Im comparing these to cards and giving reasons why the 770 is a better buy, and what it has over the 7970. I never said that clock speed is the only thing to look for in a card ever.

Did he want to do any GPGPU with his card?
