Alright so basically I'm in the process of slowly upgrading/building my own computer so I'm able to play games like APB or Battlefield 3 with little to no lag. My current computer is extremely out-dated, can barely run BF3 on low and has a hard time even playing APB properly. Current Specs: Processor AMD Athlon™ II X2 215 Processor, 2700 Mhz, 2 Core(s), 2 Logical Processor(s) Installed Physical Memory (RAM) 4.00 GB ATI Radeon HD 4600 Series -Not sure what else I should list, not even sure how to find out what motherboard I have. If you couldn't tell I'm quite new to the whole building/upgrading side to PC's which is why I'm posting this on every game forum or PC community forum I know. If people could please post what I should upgrade or replace, or even suggest a few builds for me it'd be much appreciated.
