Afternoon all,

Looking to get into mining and was advised to try LiteCoin mining as mining for BTC isnt worth it at the moment.
I've been planning on getting a media pc built for a while now which got my thinking about using this for mining too.
I know for LiteCoin mining its all about the GPU - this is correct right?
If thats correct, what is the minimum ATI card I should go for to start LiteCoin mining - I dont have a big budget as I still need to purchase the powersupply/case but was thinking of getting the R9 270 card.
Is the R9 270 card viable for mining - I dont expect to be making big amounts of money but would like to at least make a little profit if possible.
I think this card gives out around 400+ hash when checking stats - guess my question is whats the minimum hash rate needed to make a little profit without spending silly money if thats even possible for Litecoin mining.
My max budget on a card will be around £150.
I know I need to take into account electricity etc but the idea of this rig is that its going to be on all the time anyway so might as well get mining on it.
When the money situation gets better I could add a 2nd card to the rig I guess.
Hope someone can advise which will be much appreciated.
