whats a good card to mine scrypt with?
No card. Scrypt is dominated by ASICs, you won't get any reasonable results with a GPU. Try GPU friendly algos and coins (X11, X13, X15, Neoscrypt).
but flappycoin is scrypt?? Im confused??
Flappycoin is a scrypt coin with low difficulty and network hashrate. So yes, with such coins you'll get your share. But with a price of 40-50 litoshi per FLAP, it's not really worth the used energy (unless you have free energy). The other algos are more energy efficient than scrypt.
Scrypt produces lots and lots of heat, it stresses your GPU a lot. Even with a new GPU, an ASIC would be a far more viable choice due to the decreasing price per MH. Might not be profitable unless you have close to free electricity and the company is trusted.
