An i7 build will cost 250-300 more. A good x58 board like the Asus P6T cost 300. If you go with just 3 gigs of triple channel memory it will be about 100 bucks but for 6 gigs of triple channel you're looking at 150-250 depending on brand and speed.
ya well if intel stays on their schedule of putting out new processors the new ones coming out in a year will be outdone a year after their release as well. I would look at picking up the asus p6t or the evga board, just because of quality and flexibility.
It depends on what you plan on doing with your computer, and how many graphics cards you plan on running. This ussualy is the deciding factor for me when saying go with the qxxxx stuff or the i7.
The build is done and so far so good! Thank you everyone for your help on my numerous posts and threads!
One quick question: The MSI motherboard's software is showing the CPU temp at 22 degrees Celcius. Coretemp 0.99.3 shows each core of the i7 and its temperatures range between 31C and 37C. Which is more accurate? Should I be concerned?
