Oh !
Thanks Jakob (kinda new to these things) .
Idk what's with amd , overpricing all of 'em .
HD7770 for 11.5k !
It's not even faster than HD6790 for 8k .
@OP ,
HD6770 , much better deal and is not that much slower than HD7770 .
Even GTX550 Ti isn't bad either (if you want to go with nvidia) which is tad faster than HD6770
