I am in the process of building a gaming computer, and am curious what is the better route to go. Two older GPUs in Crossfire mode, or 1 newer GPU.
I plan on sticking with AMD for cost purposes. Gaming wise I play MOBA and MMORPGs.
Was thinking something like two 6670s or 6770s crossfired
a single 7850 or 7870
Get the best single card you can now, but get a mobo/psu that can support CF if you can afford it. Crossfire doesn't work in every game and can be quirky. Also, there's no reason to entirely discount Nvidia. There might be a sale when you go to buy. Anyway, I'd sugget getting a 270x over a 7870.
I agreee with getting one GPU. 2GPUs is for a 120Hz monitors or 3 monitor gaming. Otherwise, you are much better off with 1 GPU. Less power, less heat, and less $$$.
If your GPU starts to feel weak, then sell it and get a better one.
Not entirely true. I use two 760s on a single 60Hz 1080p monitor, simply because then I can run everything at max. The price to performance of two cards vs one is simply awesome. In my case, I get more performance than a £900 Titan with 2x £200 cards.
Having 2 cards has it's advantages and disadvantages. It's about whether you think whatever disadvantages can appear outweigh the advantages of blistering speed.
is there really any difference between the R9 series and the 7800+ series? seems like the R9 stuff is just a re-pimped version of the previous generation of cards.
also, what geforce card would you say is comparable to a 7870?
Single card for sure. I am always seeing people having problems with games when using SLI or crossfire. No one has problems with single cards unless the card is dead, haha. For a comparable geforce card, the GTX660. Get an OC version for a little extra oomph. I have never had a problem running anything with my 660.
