I am new to GPU programming and currently searching for the right hardware to buy for cuda 1.1 programming.
I have read that not all cards of the 8800 series support atomic operations. Furthermore a friend of my who is using a 8800 gtx told me he had a lot trouble with thread syncronisation because of missing atomic operations.
So far I have only found a thread which states that the 8800 GT has atomic operation support.
I am interested in purchasing a 8800 Ultra because I have large memory bandwith requirements. Therefore my question to you guys, does the 8800 Ultra support atomic operations and cuda 1.1. Possibly somebody knows where I can find a compatibility list of the 8800 series.
