Bitcoin Client

[x_seed]

can you guyz tell me which is the best BTC client for system with less memory?  

[Light]

I would advise Electrum - I moved over from Qt especially after having to redownload the whole blockchain again. It's pretty lightweight and offers nearly the same functionality as Qt except that it may be slightly less secure in terms of transactions as it relies on external nodes rather than your own copy of the blockchain.

Try electrum or multibit. I use blockchain.info because i can access my coins anytime anywhere
