System Lags While multitasking

[hypergamer1231]

Hello friends I am running the below mentioned setup
Mobo : Gigabyte GA-F2A55M-HD2
Processor : A10-6800K with Hyper 212x dual fan cooler
Memory : kingston value ram DDR3 @ 1600 mhz (4gb*2) total 8gb
Video Card - Zotac GTX 660 twin fan
Storage : WD 2tb 5400 rpm
PSU : Cooler Master 500 watts
Case : NZXT Source 530 full tower
OS - Windows 10 Pro 64 bit

Now the problem is games like GTA 5 take a very long time to load levels and if a game or software is installing in the background then any game would terribly lag. I have tried every thing and was wondering if this setup is too old now or what component can or shall i upgrade as I am on a tight budget.

Please Help

Installing in the background would be hitting the hard drive pretty hard, and it's only a 5400 RPM hdd.
Replacing this with an SSD would make a big difference.
Programs like steam will typically pause downloads in the background too because they will be using your internet bandwidth.

Doing anything in the background while playing demanding(some games more than others) games would be a loosing battle - even on a far better system.
