Hi i have 1k to invest on a new computer that i want to mine coins with.

what equipment would be versatile enough to mine both SHA256 and scrypt coins in an efficient wayfor around 1k?

I found this info before....would this list/info for this price still be the best for you??

You can try 3 x ATI 7850, they cost less and spent less power

MB GB H61M-DS2V 51$
CPU Intel G1610 45$
HDD no matter 55$
RAM 2GB DDR3 18$
PSU SS 620W bronze 85$
3x ATI 7850 1GB DDR5 3×175$

Prices are in Bulgaria!

This system will spent less than 450 wats under hard overclockand will give you 1200 kh/s

VGA: core 1100/ memory 1400
Miner: tread concurrency 8-9000, worksize 256, agression 19
_______________________________
390-400 kh/s single card

My rigs:

MB Asrock B75 Pro 3
CPU Intel G1610
HDD 500 GB Seagate SATA3
RAM 4GB DDR3
PSU SS 750W Bronze
3x ATI 7950 Powercolor
-
750 wats, 600-610 kh/s single card

Yes they are better but can you get 2 x 7950s for $375?
For GPU mining a quad 7970 setup gives you 2.6 GH/s.
Right now im running dual 6990s and getting 1.2gh/s.
both of these GPU setups will cost about $1600 just for the GPUs
the 6990s you can run on lower grade MBs and CPU but they cant touch the Quad 7970s
the quad 7970 so far what i have found require a $260cpu and $260+ MB but the MB would be running a x16,x8,x8,x8 on the four PCIe 3.0

If you want to water cool the quad 7970s the whole rig will cost about $3200 the dual 6990s just stock cooling cost about $2300-2500 and you could water cool that rig and get up to 1.7GH/s but that would cost about $2900-3000 all depending on the parts you want.

My 6990 setup is:
AMD FX-8120
Asus M5A97 r2.0
Gigabyte ATI 6990 (x2)
Wifi card
128GB SSD
Coolermaster 1200w 80gold
Diskdrive (for driver CDs)
Corsair 600T
I also added 4 high pressure fins on the side panel
get some 7790s, it has currently the best price/hashrate ratio and best power consumption/hashrate ratio:

If you have more money then go for 7950s.

The CPU I would use is an AMD Trinity or Richland APU. They are cheap and they can be used as an extra GPU. The A10-5800K gives about 114 MHash/s for Bitcoin mining, and about 70 kHash/s for Litecoin Mining with a TDP of 120 Watt. The new A10-6700 should be at same level or a bit above, but consumes less power. The A10-6800K should be even better but power consumption should be close to the A10-5800K.
7750s. Seem to be the most efficient.
