7870 Crossfire vs. GTX 970?

post #1 of 25
Thread Starter 
I'm toying with the idea of upgrading my rig a bit and a new video card feels like the right way to go. I know z77 has aged a bit but unless told otherwise I believe my 3570k will hold its own for a bit longer.

This brings me to my dilemma. Do I go the cheaper route and pick up a second 7870 myst and have dated hardware for the sake of saving some money (and perhaps picking up some other upgrades) or do I scrap my current card and pick up a GTX 970.

All opinions welcome, cheers.

I guess it depends what you play. In most cases, the 970 will be the better route.

7870 Crossfire will be roughly equivilant to 7970, R9 280x, R9 what 380 (I'm not sure what the 280x has been rebranded to on the 300 series). For Nvidia that's a GTX 770 / GTX 960 I think. The 970 will definitely be more powerful, plus you won't be limited to 2GB VRAM your 7870 has.

I'd say go for the 970 or a 290x.

EDIT:
Your motherboard won't properly run Crossfire, you'll be in for a really bad time. PCIe 3.0 @ 16x for slot one, slot two is PCIe 2.0 @ 4x.

Get a single GPU.

A single 970 should be faster than 7870 CF, if the game supports it properly that is.
R9 390 is about 80% faster than a HD7950 so a 970 should be twice as fast as a 7870 I think.

But you are better off with a 390 instead of a 970 in the end if you still wanna run modern games a year from now, and wan't to enjoy that sweet DX12 performance.

I haven't been playing anything too crazy, lots of DayZ lately and I just picked up Arma 3. Also,Pioneer, does that comparison still apply for my 7870? It's a myst so it has a Tahiti core not Pitcairn. I can't imagine that makes a huge difference but still.

Arma is an incredibly cpu intensive game. Make sure to set you cpu count and look up "best settings for arma 3". Upgrading your gpu won't do much for arma but will improve an any other game pretty much. If you want a rig for arma get a g3258 and overclock it to 4.8 lol

If you plan on keeping the GPU's for a bit, I'd say hold onto the 7870 for a few months and upgrade when next gen cards come out from either vendors (probably ~ Jun). If you're thinking about saving money, get the 970 or a used 290. Either should be a great bump over you 7870 even if you were to CFX.

I had 7950's Crossfired and my single R9 390 dominates it. A 970 or 390 would def. be an upgrade. It was for me anyways

he has a hd 7870 xt (tahiti core) so he would have a faster setup than a 970 except when runs out of vram or doesnt support CF at all,the 280 and 280x were not rebranded,amd instead released GCN1.2 based gpus with tahiti GPU SP/TMUs/ROPs setup,which increased Tessellation performance,improved ACEs count,reduced Bus width added delta color (bw) compression,improved the built in scaler(and probably the video encoder),plus the GCN1.1 changes to the CU

Actually, its was the R9 285 that had better tessalation. The 280/x were rebranded and were still Tahiti at the core.
