you could upgrade your cpu and mobo to a xeon e5-2670 or 2660 (cpu is close to 30 bucks) and a random ddr3 lga 2011 mobo (close to 50 bucks.) For the ram, you could get the g-skill RAM if you'd like to upgrade it when possible (buying another kit)
Is my setup great for, minimum, 1080p40FPS? (entry level setup)? Could you tell me what to change for a very budget setup? (noPSU but planning to have a 550W one for 50$)
