Avalon! Who makes those?
From everything I've read over the last 30 days the best GPU are from ATI, for mining of course.
Now of you can get ASIC chips and make them work that she best there is for mining applications but only if you have a team of hardware and software engineers can you accomplish that. I wish I was programmer cause I'd go crazy right now. This is the gold rush of the 1700's and just like then people are blind or need proof. By the time proof comes the 3rd and 4th bitcoin booms will come and go and then it will be infinitely hard to mine a single coin. I had to buy my coins cause I couldn't find a good enough rig that works. Sad, cause I put $1700 just in that one computer and for litecoins which are easier to mine it wasn't good enough and for bitcoins it would have been even worse.
On a funny note, we should start a thread on how long it takes the govt to charge a license fee to mine for coins? lol, those rats in suits won't stop at anything when it comes to tax us all every chance they get. I give them 6-12 months and then you'll have to pay a licensng fee and maybe taxes on any and all coins you find. Unlike real money or good you can hide in your pocket with digital coins you can't hide it anywhere.
And the latter is the biggest reason the govt is 100% backing digital cash, bank on it. This is a big reason digital money will make it big and for a short while all coins will go up greatly in value. The smart thing is knowing when that happens when to get out, cause eventually the govt will choose one and make the rest illegal as a matter of national security and in the name of undisrupted and a uniform and streamlined market.
Good luck to everyone!
