So I bought this PC about 3.5 years ago and has always performed fine with the games I played. But when WoD released I started getting performance issues like long loading screens, huge fps drops in dense areas (Ashran, Warspear and battlegrounds mostly). I also bought Battlefield 4 yesterday as I was craving for a new shooter but that game is just downright unplayable.
Here are my current specs:
CPU i7- 2900K 3.40GhHz 4 cores
Motherboard MSI P67A-GD65
RAM 4GB (not sure about the speed, think it's 1333mhz)
Graphics Card NVIDIA Geforce 560 Ti
Power Supply Pure PowerL7 730W
Operating System Windows 7 64B
Harddisk A9BS95 Seag 500GB ST500DM002 7200 SA3
Resolution 1080p
What would be the cheapest way to upgrade it to run both BF4 and WoD without having performance issues? My budget isn't too high at the moment, around 100-150 euros.
