One thing about buying new parts.. It usually pays off to save and get a fully decent system instead of building on a budget. Also: Getting an i3 is really just signing a contract saying that soon you won't be able to keep up with the new games. 4 core utilization is def going to be the new standard in just a moment even though its a 50/50 if people have 2 or more cores atm > Only one way forward
I second xlone, get an i5, wait, get whatever is priced best a bit later.. Hopefully you have a GPU you can use until then.?
