GPU Credit adjustment

[clownius]

Hmm bonus credit for being fast now that would go down great for my 280 and 295 lol.  I got the cache sorted on my systems finally and i only very occasionally have a spare GPU WU.  Thats generally when one is almost done.  Im real tempted to add another GTX 295 now.

Edit: Scratch all that the servers playing up again and not crunching GPU stuff......grrrrrrrrrrrrr
