so right now i have a single 1gb 4870 in my motherboard. Since my birthday is coming up in about a month, i was thinking about crossfiring, but I don't really know the pros and cons. What i do know is that crossfiring (or sli'ing) is that it has a bigger performance increase on computers that run on a bigger resolution
I run at 1920 x 1080, which is i think above average??
so tell me facepunch, is it worth getting another 4870 to crossfire with, and if so, would i be able to crossfire them on this mobo with good benefits?

this is what i have currently

do it
any other thoughts?
It would make an excellent setup, really.

Yeah I know the benchmarks are for a 4870X2, but they're similar :chef:
is my motherboard good enough for it?
i've heard some people say things about their motherboard limiting their sli or crossfire potential
Your mobo supports full x16 crossfireX :c00l:

wrong

oopsie, I forgot to look on newegg specs
remind me never to believe forum posts
so i cant crossfire then? :(
Yes you can, just at a lower speed
you could, it just wouldn't be as great as you were hoping for.
it's still fine though
**broke my automerge** D:
IMO, I wouldn't crossfire if I couldn't get the full potential of both cards. I payed for 2 cards not 1.5 .
by how much?
what if I oc'd both gpus?
There's actually a danger that one card at x16 could outperform two cards at x8.

ignore my posts at the beginning, i thought it was full x16 :Dawkins102:
it's ok :)
With a 4870 I don't think you would notice a difference between 8x and 16x. Especially because PCI-E 2.0 8x has about the same bandwidth as PCI-E 16x. And a 4870 I think uses about half the bandwidth of PCI-E 16x.
hmmmm interesting tell me more
Basically, there wouldn't be any sort of performance decreasing if you were to crossfire
Even if it was original PCI-E 8x, you wouldn't notice any performance decreases.
