I need some tips on hardware to choose.
First, what is the best mobo. I need something not to expensive that can support 4-5 gpu's.
Secondly, what is the best gpu for a price around $100; strictly ATI.
Any help would be great. Please give me more tips on hardware.
MSI GD70's are really common and can support 6 gpu's (5 x16, 1 x1)http://www.newegg.com/Product/Product.aspx?Item=N82E16813130274
In terms of gpus around 100$, there's 5850's and 5830's. You gotta buy these used because they are not in production anymore.Would suggest browsing the forums or checking out eBay.
For 4-5 gpu's you need a minimum of 1000w-1200w, even more with the setup I am mentioning.
RAM and CPU don't really matter, just draining your power.
Hope this helps,
