I went with 4g of RAM, because I have read in several places that Vista runs much smoother with 4g. And since the prices on memory are so low right now, I figured why the hell not.
So Rosewill isn't a good quality PSU brand? When it comes to who makes what better, I honestly have no clue. I basically picked all these parts blind, going on my little knowledge and the reviews posted. A quick look on newegg, and I find these... better?
Video card. I went with a cheaper card, because I honestly don't do anything that requires top of the line graphics atm. I went with a good card, but not a great card, because I can later add another and go SLI. Or I can scrap it altogether and buy something top of the line. Either way is cost effective enough I think. But what I don't know, is if I can get a better video card at the same price point upto about 50-100 more? Could use some help there.
