last time i built a computer was when Battlefield 3 was released and i ran dual Radeon HD 5850s.
that systems was lacking for BF4. the whole process took about 4-6 months because i was slowly building up the system. only recently was it completed with the parts below.
the 280x has some coil whine if you stress it with 3D Mark test. the max temp never got above 75C which is good in my book compared to the stock 95 on reference cards.
