find a deal because prices on video cards have been going up.
Ok, thanks for the reply, they are all giving me good info

So the 60 k/h, thats total i am guessing ?

i7 will give you 640KH/s when mining 8 thread and Quarkcoin.
That is what I got anyway.
Thanks again for the reply. What i meant by the 60 k/h total, i meant cpu AND gpu ? Sorry, still relatively new to all this

Yes, this 8 physical integer core arc does best executing 8 threads.
That doesnt have the cpu on its list

The 8320 is simply a lower verified clock 8350. Same silicon, tons of headroom. Often, they aren't even lower bins (relative quality rating of the chips) than the 8350's. The vast majority are capable of 5 ghz + when installed in a decent motherboard and OCed by someone who knows what their doing.

Ok, change of plan, i am possibly gonna be purchasing http://www.digitalpromo.co.uk/amd-fx8320-8core-35ghz-socket-am3-16mb-cache-retail-boxed-processor-p-6962.html and http://www.amazon.co.uk/Sapphire-GDDR5-Retail-Pci-E-Graphics/dp/B00FOQZZAK/ref=sr_1_1?s=computers&ie=UTF8&qid=1388469555&sr=1-1&keywords=280x. I am hoping to be cpu coin mining from 6 of the 8 cores, (may do 7 cores), and also gpu mining as well. What sort of k/h rate will i be looking at, because i cannot make heads nor tails of the hardware wiki page (identical model numbers, same core clock and mem clock yield different k/h rates).
Thanks in advance

you will be around 710-740 / 280x depending how good it is, if your lucky, higher. sapphire card should do 720+ with same settings u see on that hardware wiki. TC 8192 or 11200 works best for me.
Thanks for the reply, any idea what i should be pulling in for the cpu ?
MEPH
Should be getting around 60 kh/s @ ~ 4.1-4.2 ghz when you utilize 8 threads. In my experience, there's no real reason to leave a core idle, the speed decrease from loading all cores is minimal to non-existent on this arc, possibly because it's still not utilized as effectively as it could be by the majority of CPU miners.
That doesnt have the cpu on its list

Bump, still hoping someone can give me another rough estimate for my cpu

no idea whatsoever. best guess 40. that is based on 0 experience and is completely a guess based on how much my NVidia/i5 setup changes w cpu on while scrypt mining. cpu mining may not even be measured in KH/s, I wouldn't know. gl

I don't know your budget, but at least have 2 or more cards per setup. At least a HD 5870, HD 6950 or HD 6970 for starter cards. Ideally, HD 5970, 6990, 7950, 7970, 7990, R9 270X, R9 280X, R9 290 and/or R9 290x. Unless your going to CPU mining, at least a low power dual CPU. If a high end CPU and CPU mining, then a low end Core i7 or AMD 8 core FX series. Minimum 8GB RAM, 16 GB suggested if more than 2 GPU cards.
Does 8 -> 16GB actually make any difference? I'm running 4x 280x at around 720kh each with 8GB
you want either a huge fully modular 1300w (ish) or 2x 750w modular with 2x pcie 8pin/6pin connectors (4 total) single rail psu
jump the green wire to any black wire on the 2nd psu's 24pin atx connector to trick it into thinking the system is on. power both psu's on at same time, then boot rig. run any HDD from the same psu as connected to mobo.
power pcie risers from the same psu as the 8/6 pin pcie power is coming from for each card.
you will need powered pcie risers for > 2 cards, you will want powered risers for all but 1 of your cards, this will prevent any loopback through the pcie bus.
be sure the risers are the kind with the power wires cut which lead back to the mobo, see example here:
http://forum.feathercoin.com/index.php?topic=2193.0 - [Guide] Homebrew powered risers.
most of the recommended suppliers of pcie risers will have this done correctly.

Nope
4GB is enough for gpu mining.

I am running 5x r9 280x on 4gb 2x2 gb gskill with no performance hit (the 5 card rig runs 1% slower than 2 card rig, not sure why maybe the ram /?)
amd Sempron 145
3x 750w
7200rpm sata 6 500gb hdd
xubuntu
so I highly doubt you need 16GB, but perhaps if you are overclocking or on windows it affects performance more. or on certain types of coin. I haven't tested thoroughly enough to say for sure.

The problem with the 5870's is the price for 2nd hand ones on ebay.. been watching a few pastw eek, and they are going for £150+ each.. i can buy a friends 5830 for £40..

DO IT! You will learn more about mining in process and you will know what exactly you want after a day using it MEPH
