TMRN, I liked the part where you ask people for their considerations on your hardware selection and then proceed to tell everyone that their advice is bad and you know better than them. Honestly...
Unless you only wanted input regarding the following:
I mean, is the extra ten dollars to get the Gigabyte 6850 and the extra 8 dollars for the Corsair XMS3 RAM worth it?
If that was the case you might have wanted to explicitly tell people in advance to stfu so they don't waste their time, unless all they want to discuss are your GPU and RAM selections.
There are some glaring issues with the combination of components you're currently planning to order for this system, but said issues have already been addressed by posters and you told them that they're wrong. So at this point I feel it's most appropriate to advocate going full steam ahead with this silly gaming setup.
P.S. How can you even contemplate dumping money into a new gaming rig without even considering the fact that you're playing games at a laughable netbook resolution? It seems painfully obvious that a display upgrade would be a top priority for improving your gaming experience.
*Edit*
P.P.S. After MIR the Gigabyte 6850 is $10 less than the PowerColor.
