As you may already know, Evga has "Step-Up" program which allows you to trade your older card for a newer card and you only pay the difference. I guess I will stick with this for now and trade it in for a better one later. Maybe get a 280 version. Thanks for the advice though. I think it's going to arrive soon.
By the way, what's the difference between current model and this "55nm version"? One more question. Can you use the hydro copper model with a air cooling system? or do you have to have water cooling system? I only saw it for the first time and I think I saw a couple of holes on the copper pannel which seem to be working with a water cooling system. (I know almost nothing of water cooling system) And what are those "ring-like" things in a small bag that are a part of the package?
