Making your purchase dependent on a future difficulty drop is a very bad idea.

It could rise instead of drop.

what worse could happen is bitcoin price crashes and you are left with some oversized heaters...

Is to get an estimated profit only. thats not my main buissness.

im praying for the price to go up

i need the equptment. i do 3d animations. mining will be my side buissness. to pay bills.

the worst thing.. that i will sell one or 2 of the rigs. bc i will still use the other 10. for 3d animation.

Yes, I don't see the difficulty drop as much any time soon unless in case of a BTC crash. All the more so since we have people like you who explain how profitable the current difficulty still is
Just my 0.02 BTC

Very impressive rig !! Wish i have one of those....

[happycamper]

Difficulty and price are closely related.  i.e. When price falls, mining is less/no longer profitable.  People leave in droves and hence the difficulty drop.

If you are betting on difficulty to drop, adjust the bitcoin price in the calculation by the same percentage drop if not more.

I know which is why im really having a hard time trying to spend money on a faster card than my stock 5830...

[bitcoiner49er]

There is no way that case will keep will keep 4x cards cool unless they are runnning in a freezer. Hell my HAF932 has issues with dual gtx 470's if it's hot out.

1st the case is open.  2nd i cuted the plate that holds the motherboard, leaving enougth steel to keep integrity . 3th the mining/render rigs r on the basement. where i have A/C and i leave on a place where the average temp is 6 °C.   the cards run now at 56°C~66°C  and now the temperature of my building is better the other ppl thx for it.  an average of 16°C. without turning on the Calefaction.

note i have 6 running now. 6x4 gpus stucks at customs.  i m8 need to pay a fee to get them out. exceded the limit per person on the import. lols

EDIT:
for those having problems with the 4th CARD and this MOBO  try upgrading the bios
you can find them here http://www.msi.com/product/mb/890FXA-GD70.html#?div=BIOS try with 1.6 or higher.

[Doedskvad]

Impressive rigs! Do you use them to play somtimes, too?

[TwistedPair]

If you're doing 3d work on it, wouldn't that mean you can't mine during that time and reduce your income?

[Doedskvad]

Yeah sure, but if he's got like 6 rigs right now, using one of them for a few hours for some heated FPS battles wouldn't cost him that much.
