Well after getting a new graphics card (7770) I can mine bitcoins at around 120 - 180 Mhash/s Depending if I run it at full power or not.
Now I thought I would try and mine myself an address using it but the miner just seems to not work.
Using Vanitygen (Linked below) oclvanitygen I set it off mining with reports of it mining at around 4MKeys/s but nothing was showing up after 5 mins worth of time(I tried a simple prefix of 1r).
I then tried using just vanitygen64 and in seconds it found an address.
Does anyone know why?
