Hi, guys. I have about £2500 to invest in litecoin rigs. One of the rigs is a replacement for my Sandy bridge rig and will be a gamer/miner, I will use it to game maybe 4 hours per month. The other rig is a cheap AMD platform. The haswell rig will run with my 7970, a 7950, and a 6950 I will purchase. The AMD build will run 4 7950s and a 6670 or super-budget card for displaying the screen w/o compromising the stability of the cards that are mining. Is it possible in cg miner or guiminer to only mine with four of the five Gpus I will have connected?

Here are the two builds, can they be improved?

Gamer/miner
I5-2500K
Gigabyte GA-Z68X-UD5
XFX 7970 (owned)
Sapphire vapor-x 7950
HIS or Sapphire 6950
Corsair HX1050 (owned)
Lian li T60
Optical drive, win7 h

Edit : updated build

The 7970 gives around 600kh/s, the 7950 should give around 600 too and the 6950 will get 400-450
Total hash rate : ~1600kh/s

AMD
Athlon ii x2 270
Gigabyte 990FXA-UD3
4gb ram
4x sapphire vapor-x 7950
6670 (to power display)
OCZ 1250W psu (might get a 1475w to be safe)
Optical drive, win7 hp
7950s will give around 600 each so 2500kh/s should be achievable. 6670 will give around 50kh/s should I decide to mine with it too.
Total hash rate : ~2500kh/s

Combined hash rate: ~ 4100kh/s

Thanks for your time!

You may want to rethink the Gigabyte 990FXA-UD3. I have one and it is difficult to mine with unless you are planning on using extenders, also the passive cooling on the board leaves virtually no space between the heat-sink on the board and one of the GPUs.

Why is it difficult to mine with? Also what am3/ am3+ board would you recommend for use with risers?

I'm glad someone mentioned mobo issue. I hate that mobo. I have about 10mh, about to be expanded to 15mh in a few weeks once I settle into my new home. You can't go wrong with MSI Z77G60. Except you'll have to change your processor to an Intel 1650, preferably an Ivy Bridge proc if you want that last PCIx16 to be active.

Will any ivb CPU work? I will check out the msi board and G2010

Edit : Can I crossfire the 5 Gpus? Edit : build updated
