haha thanks!
i'm kind of new to thisy
also i have one more question:
does the AMD HD7990 GDDR5-6GB
Dual GPU DVI/4xMini DP Graphics
Card GV-R799D5-6GD-B really runs at 1250khash/s (1.25mhash/s .-. )

?

yep...
the card itself has 2 gpu's on board... and for scrypt mining (litecoin, nyan,...) a lot of memory...
so yeah it can handle the hashes...
but I think that is a really expensive and powerconsuming card...
the $/kh/s for this card is not so good (I think)... but it will save some place on your mining rig (1 card instead of 2)
