Yeah, the fanbois are coming out like flies to roadkill. Now, if the 295s are dropped to 200 bucks a pop and you were on a tight budget, it would be a different situation.
Also of consideration, if your motherboard supports more than 2 PCI-E slots, you have the option of adding a third card in the future, but dual 295s would be the end of that upgrade path, as I am quite sure there is no Hexa-Sli support yet, outside of the Tesla desktops. I can't really fathom needed a third 5870, mind you, but I also can't see into the future... YET.
Stick with the order you have if you can't get the restocking fee waved. It is an excellent build (one of the best gaming rigs that can be built atm) that will serve you very well for a long time to come, I know I would love to be on the recieving end of that gift, hah. Interested in adopting a 30 year old child? I change myself and can cook Macaroni and Cheese, in nine minutes flat, yo.
Disregard posters that don't bring at least a modicum of respect and thought to their suggestions, they are pretty easy to spot. 😉
