Re: Can someone help me calculate the Mhash for this setup?

GPU is really the only thing that effects Mh/s, just go off that chart. Also take note that many values are from overclocking (clock speeds are shown on the chart).

fascistmuffin: I was looking at that chart earlier. Can I just add up the Mhash speeds? (ie speed x 3)
Really nice setup

You don't even need 30 GB, max you need is 7 GB,
You don't need that good of a CPU.
2 GB RAM? I'd probably only get 512 mb or 768.
You don't need 850 wawtts.
You don't need a badass case.

nofear1999: Are you sure about the SSD? I thought that might be the case also, but I wasn't quite sure. What would you recommend for SSD, CPU, and case? I am concerned about cooling, but i figure if all else fails I could always just put it all in an open from and point giant fans at it hahaha
Also, on AMD's website it calls for at least 1GB RAM to run the Radeon HD 5970. But since I am going to be running 3 of them, won't I need more than 1GB RAM? And a better CPU?
Also again, AMD calls for at least a 650Watt power supply, and calls for a 850Watt power supply if you plan to use ATI CrossFireX technology in dual mode.
Here's the System Requirements from their website: (http://tinyurl.com/27vndvz)
- PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
- 650 Watt or greater power supply one 75W 6-pin and one 150W 8-pin PCI Express® power connectors recommended (850 Watt with two 75W 6-pin and two 150W 8-pin connectors for ATI CrossFireX technology in dual mode)
- Certified power supplies are recommended. Refer to http://support.amd.com/us/certified/power-supplies/Pages/listing.aspx for a list of certified products
- Minimum 1GB of system memory
- Installation software requires CD-ROM drive
- DVD playback requires DVD drive
- Blu-ray playback requires Blu-ray drive
- For an ATI CrossFireX system, a second ATI Radeon HD 5970 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required

this made me lol, but I would agree. If i was building for mining, and mining only, I wouldn't spend on the extra.
iambean: Thanks for the second lol Is there anything on the PC that will bog down the GPU? Like if I have too slow of a CPU, couldn't that cause a kink in the system?
What do you guys all think of these modifications?

I'm only concerned that the RAM/CPU aren't enough to handle 3 of the Radeon HD 5970's. And that they might need a bigger power supply. What do you guys think?
