okay- so no cpu mining.
now, sense the level of bitcoin mining is so high, would it make more sense to mine litecoins?
I've had issues running CGMiner on 13.4, if 13.6 fixes this then I am willing to update.
And I have another question..., Where is Pooler's pool?
EDIT: yet another

question...
By "not pay at all" do you mean pay less? I was running my apu's gpu and my 7750 on two workers and I just got 0.00002 LTC in only like half an hour...hmm (i am clueless)
EDIT2: last one...Some people seem to be Solo Mining on what seems to be weaker hardware...would this be a bad idea as well? (I will assume yes if unanswered P:)
-My god, The Wiki said my mother's pc with just one 7750 would only get 123 MH/s bitmining and it does 150...and with litecoin mining it gets 180Kh/s...I think this is good...-
Not paying at all means no income from mining. Some pools do not pay out when your hashrate is too low.
Solo mining on weak hardware is pretty much the same as buying a lottery ticket. The chance you will mine a block is so low that it may never happen.
The 7750 you mention is being made in several flavours. Some card manufacturers do not use the reference design cards and create their own, making something more efficient. THerefore, they can usually run at a higher clockspeed and they will sell them set at that higher clock speed by default.
Most 7750's have a 800Mhz default clock speed, but 825, 850, 875 and even 900Mhz flavours are available. Usually indicated by adding something to the productname, pointing towards that higher performance. "OC", "Ultimate", "Boost" and many other names are being used.
A stock, unflavoured 7750 will do around 125Mh/s in Bitcoin, but this can go up to around 150Mh/s when running at 900Mhz.
