I currently have a Powercolor 7870 HD card I run. I wanted to get a new 3GB card but thanks to mining bs they all skyrocketed. So I am going to look at getting a second 7870HD card to put in my rig and run in crossfire.
Seems like the cheapest option. However the GHz edition cards if I crossfire that with a standard 7870 will that work? Or do they need to be the same. I have never run a crossfire setup before.
I have an adequate board and PSU for the crossfire, ASUS Crosshair V Formula Z board and Thermaltake 750 Bronze plus Modular PSU SLI/Crossfire capable.
I am only using one monitor, no plans for multi screening. Just want to be able to increase graphic performance going forward for the new games coming out at the lowest cost point.
My knowledge of crossfire is limited but I would imagine having 2 GPU's double the VRam and Bandwidth for a lower cost would be better then 1 3GB card that is really expensive right now.
Actually you can buy an Asus DCII R9 280x 3GB for 328.99. I would get that. Especially because you have a very bad PSU. It probably won't be able to support CF. And Multi-GPU setups on one monitor can cause screen tearing and frame stutters.
Why is my PSU bad? I have never had a single issue with it. I bought it a few years ago. Unless you mean it just doesnt have the juice to run newer cards in SLI/Crossfire. I cant see how it's bad. I have run 5 Drives, multiple brands of cards, a X6 and 8350 against it, never had it throw me an issue yet.
And where can you get that card for 328.. because its not on Newegg/Amazon/TigerDirect for less then 500. So thus I would rather spend 200 and get a second 7870 then drop 500 on one card because of Bitcoin nimrod markups.
Well, your 750W PSU might hold 2 cards... I say "might" because you mencioned 5 drives running... Anyway, imo, 2*7870 is cheaper than one R9 290 (but a bit more expensive than R9 280-7970). I think it will give you more firepower 🙂
