Basically these are the items I already have: 1 TB Caviar black 1TB Caviar green Noctua Cooler DVD drive Corsair TX750 I can't really decide between these 2 options: 1. i7 920, Gigabyte UD5, 6GB of Patriot memory 2. i5 750, Asus P7p55d. 4GB of Patriot memory I was going to get an XFX 5850 for either build, is there a better deal, maybe the 5770? My main question is, the i7 build would be about 300$ more than the i5, is it worth it? I plan on gaming and doing video encoding. I read the anandtech article about i5 mobos dying, I know Bindi said not to worry, but I'm still kinda nervous about going that route. Also, I have no real idea about how to overclock, is it as simple as going into the BIOS and raising the CPU multiplier, do I have to adjust voltages? I was thinking of trying to get either CPU to 3.6 with the noctua, just wanna make sure its easy/safe. Basically it comes down to is the i7 going to perform that much more than an i5, to warrant 300$ extra?
