confused on 2 gpu's

[gmanamaya]

Hello yall. considering upgrading my GPU, I have gotten loads of great feed back and advice on what to do with my current build, thanks again to the great community here on linustechtips. I was just looking at a couple cards for my rig, one of the EVGA is a 1080 ti 11gb priced at round $800, and the core clock speed is 1.56GHz and the boost is 1.67GHZ, 

 

the other card is a Asus - GeForce GTX 1080 8GB ROG STRIX which is priced at $540, but it's clock speed is core 1.67GHz and it's boost is 1.83GHz, so is this lower priced GPU stronger higher clock speeds running better graphics wise? the speeds are throwing me off, but I see the EVGA has 11GB and the Asus is 8Gb, is that the numbers i should be basing the performance on?

 

CPU:           Intel core I7-3770k 3.50 (not OC) LGA 1155
MB:             ASUS Sabertooth Z77 Motherboard
Bootsys:      Samsung SSD 840 PRO 120 GB
Storage:      Seagate HD 7200RPM 2 TB
GPU:           Nvidia GTX EVGA 980 (had 770 EVGA replaced 2-3 yrs ago free)
RAM:           CORSAIR Vengeance 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
CPUCooler: CORSAIR Hydro Series H100i Extreme Performance Water/Liquid CPU Cooler
PSU:            CORSAIR Enthusiast Series TX850M 850W ATX12V v2.31(power supply)
Case:           Corsair Carbide Series Air 540

Different GPUs have different amounts of shaders, texture units, and raster units, and also have different memory bus widths. So you definitely cannot just look at clocks.

 

The 1080 Ti is significantly faster than the plain 1080.

[rhyseyness]

Clock speeds and memory speeds are almost irrelevant when comparing 2 different model graphics cards.

Use performance benchmarks to judge which card is better value/better performing.

A 1080Ti will beat a 1080 in pretty much any workload, regardless of the clock speed difference you describe.

I know Id be running a risk and it can go both ways, but im looking at ebay list of this card used and they sell for almost 600, would these cards still be under warranty with EVGA? and be a good idea to take a chance buying one from ebay or just dish out the extra 200 for NEW one.

 

and or would it be worth it to jump up to a EVGA GeForce RTX 2080 XC BLACK EDITION GAMING, 08G-P4-2082-KR, 8GB GDDR6 that is priced for round 800 too, or does the 1080 Ti still out perform this card too?? they both are same price

The RTX 2080 and GTX1080 Ti trade wins, with the former winning more often than not. I believe it out performs the GTX 1080 Ti at higher resolution.,,,,but it depends on the game engine used I guess. They're pretty close performance wise that is....

Shouldn’t be comparing those two cards anyway. Completely different. Get the best card you can afford. 

 

Then work on upgrading the rest. That cpu is gonna struggle in some games especially with those cards.
