So my local shops dont have the selection as newegg etc has i had to go with what parts i could find.
Gigabyte 990FXA-UD5 Only card i could see with spacing to fit 3 cards in a 7slot slot case without risers, other beeing asus formula cards but they were twice the price
3x Gigabyte HD 7950 3GB GDDR5 seems to have better cooling than the other cards and should fit fine? my other options are
HIS HD 7950 IceQ Turbo 3GD5(100$ more)
HIS HD 7950 Fan 3GD5(50$less)
SAPPHIRE HD 7950 VAPOR-X 3GB GDDR5 (same price)
SAPPHIRE HD 7950 3GB OC GDDR5 (50$less)
AMD FX-4100 Black Edition 3.6G cheapest am3 cpu i could find
2x Kingston DDR3 4GB 1600 8gb optimal for ltc mining?
case Tempest 210 120x2front/2x120side/2x140top should be enough?
XFX ProSeries 850W 850 should be enough? if not i have a corsair ax1200w i could use.
16gb flash stick
Warranties are important as you'll likely mine with this card until it dies. Especially in a 3 card non riser'ed system.
You can find cheaper AM3s than that, literally pick up some $40 thing.
8GB is a bit overkill still, even for litecoin. Its cheap so doesn't matter.
Try and find a case with a 200mm+ side fan, as you'll need the massive cooling for those GPUs.
850 should be fine, but dont expect it to last more than 2-3 years.
Buy a cheap 80GB refurbished hard drive from ebay, like $25. Same price as flash but can sit inside.
