a faster core speed is more valuable than the memory. do not go into the deep of specs. just choose four or five cards around our budget and then look for real world benchmark on benchmarking sites and compare them and choose accordingly.
i have purchased sapphire 5770 for 6900 rs. if you want to overclock you should invest in a good ram from corsair and a good motherboard from gigabyte with all solid capacitor design. and for cpu cooler consider cooler master.
