I am brand new to the bitcoin world. I have been trying slush pool mining on my laptop getting around 4.5 Mhash/s which is pretty bad, but its more for learning than anything.

I don't really want to invest in a full rig, but I would like to throw a http://www.newegg.com/Product/Product.aspx?Item=N82E16814102932&Tpk=100282XTREME (I know its out of stock, may get it on amazon) into my desktop. Its a relatively cheap card, but looks like it will get 250 Mhash/s. My mobo looks to be able to accommodate it and my 525W PSU would work too.

I run Ubuntu linux 9.10. I tried to install poclbm, but it does not seem to be available for my version of Ubuntu. Otherwise, I would be playing around with mining on linux. In two days Ubuntu 11.04 will be out. Will there be a compatible version of the mining softwares available for Ubuntu 11.04 (I plan to upgrade)? I would like to get one of these cards soon. Any tips or advice would be appreciated. Just keep in mind I don't plan on spending hundreds at this point. Thanks!
