Need a new PC that will play bf3 and mw3 flawlessly. built my current pc in august of 07 (amd athlon 64fx62 or something like that an asus m2ne sli with 2 9600gt video cards) Its outdated and barely plays black ops.
would like to not "overkill" high priced stuff i dont need (I.E. 6 core instead of 4 core or 12 gigs or ram instead of 8 if it wont really help me any in gaming applications?) so that i can get as good of graphics cards as i can get.
would like to go water cooled due to using a wood stove in our home and high ambient temps.
so would like to get a ssd hard drive for windows 7. Dont care about bells and whistles such as lighting/led in or on the case and stuff like that, so a plain jane case is fine as long as everything is good, airflow wise.
there is so much stuff to choose from i dont really know where to begin. buddy of mine just built on with an asus m4a89td pro and an amd phenom II x6 1100t with dual ati 5870's and he seems to be really happy.
cant think of much else except i wont to do it for as reasonable price as possible.
