I want to build my own pc for the first time. $700 is my maximum expenditure. i would like to get an amd but im never sure if it is worth it compared to the intel range. i cannot unederstand the difference; AMD on average seem to have better performance on paper (4.0 Ghz for AMD vs the 3.4 Ghz for i7's), but even from my own experience ive found that intel runs smoother, please explain if possible. the idea would be that the pc remains upgrade-able without compromising on the performance. I want to install BF3 (and eventually BF4) on it and play without any lag as that is the problem with my current laptop (hence the upgrade to Desktop). enough is enough now. thanks for all the help.
