a while ago i upgraded my shitty dell inspiron 580s. its a slim so i was very limited on everything i bought. i got a 400w power supply then got a new graphics card amd r5 200 series. i guess when installing these i bumped around the heat sink and the thermal paste was creating the problem i had which was overheating. i thought it was just because i added more stuff so itd need better cooling so i bought 3 fans. installed them and nothing. i modified my case for better airflow. still nothing then i bought thermal compound. applied that and it worked. my temp stays around 40c no matter what i'm doing. even gaming. at idle its 20c. but my gaming experience or whatever really isn't all that good. i still gotta run games on the lowest settings. the question i'm asking is WHAT ELSE can i do to get more performance. i'm pretty sure the only thing left is a processor upgrade. if so what processor is compatible for my pc. around $60. the processor i have now is a intel pentium r G6950 @ 2.80ghz.i also have 4.00gb ram 3.80 usable.any help would be greatly appreciated!
