MSI GTX 970? Worth it? Chill dude 15/02/28(Sat)01:23 No. 21673 ID: a38c5e

File 142508299165.jpg - (24.15KB , 300x225 , 14-127-832-Z08.jpg )

Thinking about getting 2 MSI GTX 970s for sli. Going to have 4 moniters hooked up to them. (2 17' 1 24' and 1 52' moniter). Anything I should be aware about before buying these or any other recommendations?

Why waste your money on SLI when you can go Crossfire and get better performance for less?

Which AMD do you compare this with?

970? You mean the "4GB" cards that are actually only 3.5GB cards?

The R9 290X seems to offer roughly comparable performance at a lower price point, and has 4GB to the 970's 3.5GB (a difference of 7GB vs. 8GB if you're looking at two cards).

no, a difference of .5
Crossfire and SLI don't give more frickin vram, dingus.

Each card gets access to its full RAM. Unless you're dealing with a game that won't run in crossfire mode, that means you count RAM on both cards.

Fallacy, it is a shared resource between the two cards.

Both are technically correct. Each card gets full access to it's RAM but the image is cloned across both sets of memory so you are limited to the size of the smallest memory array. It's the video card equivilent of Raid1.

Now if you were a *nix user it is possible to run AMD cards in Raid0 with customer drivers. Or, you can go for the killer and run an AMD-APU, AMD-GPU & nVidia-GPU in crossfire but it'll still be limited to the smallest VRam size. Crossfire offers more flexibility in its configurations at the cost of performance where as SLI is limited due to the hardware.

No matter how you cut it though you're still getting 25% more VRam with AMD and the performance benefits of SLI are limited as the only way you can upgrade it is by replacing the entire array.

Technically with the 970 you're getting the same 4GB of RAM, but the last .5GB will drastically decrease performance to the point that it performs worse than if the last .5GB wasn't used at all. This is why so many games are special-casing around that last .5GB, but good luck if you're playing a game that doesn't have a special case for that model.

I dunno, if I was dealing with a piece of hardware that was bastardized to that extent I wouldn't trust the entire product, but fanboys are gonna fanboy.

First the .5Gb was locked unless you were a special case (specifically backed by NVidia and actively excluded anything to do with AMD). Then they unlocked it when people realised they weren't getting what they paid for and could potentially sue. Now developers have to deliberately avoid using that extra .5Gb to avoid shit-canning performance.

It's the prequel to nVidia Gameworks, shit-canning performance all over the place so they can lock developers into their product with the promise of "extra performance".

Gameworks is also about shitcanning performance on older Nvidia cards too. Even if your older card is vastly more powerful than a newer card, the newer card will get better performance.

The only reason developers are using Gameworks is to get a taste of that sweet, sweet Nvidia development monies. Having Nvidia work for free on your code is the same thing as paying a developer cash to hire someone to do the work. Nvidia just cuts out the middlemen.

It is not worth it
a couple of GTX 970's is still no match for a GTX 980 just save a little bit more and you can run any kind of games you want with a single GTX 980 than having to crossfire your cards. Crossfiring does not give you much performance it always depends on your game and how shitty it is optimized the most you will probably get is about 10-20 fps increase that is a pretty shit deal if you ask me, Just saying OP
