Hi, everyone.
I was browsing trough a local second hand website and found a guy that was selling:
-Asus 7970
-Gigabyte 7970
for €130.
I currently own a gtx 760 but if i decide to buy a second 760 i will have to but a new mobo since my asus z87-k only supports crossfire and not sli.
I would like your oppinion on this.
Should i buy them if i have the money to spare?

Extra VRAM will certainly help when it comes to mods, so changing to an HD 7970 may be worthwhile.

An important point to note about Crossfire is that VRAM isn't scaled. In other words, if you buy two 3GB cards, you still only have 3GB of VRAM, not 6GB. If VRAM is a priority, Crossfire wouldn't help, even if your motherboard was suitable.

Rather than going for an HD 7970, have you considered selling the GTX 760 and buying an R9 290 4GB?

As stated, the second PCIe slot only runs at PCIe 2.0 x4, which will bottleneck a Crossfire/SLI set up. In my opinion, Crossfire/SLI simply isn't an option with your motherboard, so if you want to upgrade, sell the GTX 760 and buy a single, powerful card.

That said, a GTX 760 is fine for the most part, assuming you play at 1080p.

actually i have a single 7950 + 3570K and i can maxout any well optimized game with out AA @ 55-60 FPS with my OC

so with a 760 im pretty sure u should have near the same results IMHO u should sell the 760 and get a single GTX970 that is the best bang for the buck no doubt and it will run 100% problem free

I already knew that my mobo would be a bottleneck, but according to http://gpuboss.com/gpus/Radeon-HD-7970-vs-GeForce-GTX-760 the 760 barely outperforms a single 7970. I really am on a tight budget but since my parents pay the electrical bill, power consumption is no concern.
I also could just pass on my 760 to my dad (he's in need of a new buisness pc that will last him a while).
So, i really don't know and asked oppinions.

Yeah, i would either choose the 7970's in crossfire or a 970, but that is out of my budget range.

well than u should wait for the GTX960 or AMD R9 3XX
also AFAIK

7970=GTX770

7950=GTX760 in terms of performance

with my 7950 @ 1300/1950 and a 3570K im maxing out every game out there without AA @ 60fps

so i think your 760 can hold up for a couple of months

GPUBoss isn't the best way to compare cards, as the scores are based solely on compute performance and are far too generic. For example, a GTX 760 scores an 8.3 for "gaming; real world tests using the latest 3D games". Ask yourself, what exactly is that score based on? What games were tested?

A better comparison is to check how both cards perform in the games you currently play, and want to play. Use trusted sites such as Tom's Hardware, TechPowerUp or AnandTech.

A final thing to remember when making comparisons is that frame rates are relative. If you have a 60hz monitor which can't display anything above 60 fps, then the fact that an HD 7970 runs a particular game at 100 fps is irrelevant. All it's doing is wasting energy whilst making more noise and heat.

I know bro, but i could use the extra vram (i like to play skyrim and gta iv with a sh*tload of mods)
Or, should i only get a single 7970?
Also, i have a monitor that's overclocked to 75hz and my average skyrim fps is 40.

I already knew about crossfire not adding any vram, but would it be worth it to buy a 7970 now and upgrade in 1/2 a year?
Honestly, i think i'm just going to stick to my 760 and (if i have the money) buy the 970 when the 8gb variant comes out

I'm going to wait 'till something more powerful comes out that's decently priced
