Question:
I currently have a ATI 7850 as my current GPU. I see the new r9 series have come out, at the pricey cost of roughly 400~ for one of the "better" models like the R9 280x.
I was wondering if it'd rather be worth getting the R9 280x or simiply another 7850 to run in crossfire with. I'm assuming if I got the 7850 and run it in crossfire, by the time I can't really play games on ultra anymore it'd be time to upgrade and the R9 series will already be much lower than what it is now. But is CrossFire worth it? I'm mainly considering that option since I have a triple monitor setup now.
Most AMD cards anybody here would buy support AMD's Eyefinity which allows you to do up to six screens on certain cards and setups. For your setup and with any R9 series card, you would probably use one if not two of the DVI ports (if you don't want HDMI) and DisplayPort for three monitors (DisplayPort is required as the third display for triple-monitor setups vOv). You can check out the Eyefinity page AMD has for more in-depth explanation, but it's clearly a bit aged.
If you're actually considering using CrossFire, you should probably at least check to make sure your motherboard is built for the CrossFire setup you want. Most motherboards won't have 4 PCI-E x16 slots all at x16 speeds. They'll be at maybe x16 x8 x4 x4. If you plan to only use say, dual CrossFire, then you only need your first two PCI-E slots at x16 and x16 and you can disregard the others, if any, assuming you won't use them for anything as demanding as graphics. This is certainly important if you want to jump up to an R9 290 or 290x where CrossFire is actually done through the PCI-E slots rather than a CrossFire bridge. If you want four full PCI-E x16 slots at x16 speeds, you'll have to do a lot of searching around, and I'm sure your wallet wouldn't take too kindly to it either.
Oh, and just another thing, the stock R9 270 performs about as well as the GTX 660 and also supports the Mantle API. Just look at benchmarks and see how things will stack against one another at stock clocks.
Yeah I plan on waiting a few months - but if I did crossfire it'd be with just two 7850's, and I'm assuming it'd be with the bridge (my mobo does support all this, and also just has two pci-e slots anyway)
I currently run trip monitors how you explained NneYaTano, I'm just thinking it'd be nice for the extra graphical power now, and that I might be able to actually play games decently across all 3 monitors if I wanted too. Right now my FPS gets down pretty low (in the teens, sometimes when I'm lucky 20's) when I try, I'm assuming two GPU's will help increase the power for that.
Needing a price check on my current PC that I'm gonna be selling. Have two possible buyers already but need to find a fair price and I've been out tune with PC parts for a long while.
Processor AMD Phenom(tm) II X4 965 Processor (4 CPUs), ~3.42GHz
Memory 4GB DDR3
Hard Drive 500GB
Video card AMD Sapphire 6870 1GB DDR5
And the case is an Antec 300 if that matters at all. Thanks niggers.
