Nothing wrong with a little friendly competition

On a side note I have about 150 I need to spend from amazon.
Can anyone recommend a good card for mining.
I have been doing a little research but I like quote from people that are actually using them.
Trying to join up with my measly 144 mhash but keeps throwing back a problem communicating error.
I triple checked my information to make sure it was correct.
Anyone else with this problem.
We shall be fighting on the leaderboard..
