lol it looks like me and you are gonna have almost the same build. i have the e6300 and i love it. in march i am going to get that gigabyte ds3 along with the exact ram that you are going to buy. but maybe i will get 2 sets of 2x512 for a total of 2gb, depending if it will fit in my budget. but i will not get the same videocard, i'm gonna get the geforce 8600ultra when the come out sometime around march.
everything on your build looks pretty good. you should be able to get some pretty decent clock speeds if you oc. i will reccomend the artic freezer 7 pro because it is cheap and it works very good. i was using it on my p4 prescot and it lowered the temps from 60c to 47c. by the way what is the average and max temps for a core 2 duo???
well why not get 2 sets of the 2x512. the motherboard has 4 ddr2800 slots. wont it be faster if he just got the 4 sticks of 512 instead 2 sticks of 1gb. unless he is planning to get more than 2 gb's of ram.
