I recently bought a gaming desktop from a friend, has the following;
CoolerMaster TD500 mesh
MSI Gaming B450 Pro Carbon Max Wifi
AMD Ryzen 3700X with the wraith cooler
MSI Gaming X Trio RTX2070 Super
Corsair Vengance LPX 16 gig running at 3000MHZ
WD Blue SN550 500gig M.2
Seagate Barracuda 2TB HDD
Silverstone Strider Gold 650W
Anything I should be looking at upgrading?
I've just put another M.2 500Gig Micron SSD from a XPS laptop that I had lying around.
My brother who's more of a gamer than I am advised to upgrade the ram and maybe PSU. Will be looking at a RTX3080 later down the road as well.
Should also mention that I'm playing on a 1440P 144HZ IPS ACER and I've got a LG CX if I'm ever inclined to play on that.
If it's only new to you then just use it.
It's a more than capable 1080p gaming machine at the moment.
Over the next 6 months you may find some deficiencies in the PC so upgrade those.
RAM is ok for 3700x and 16gb should be adequate too. If you upgrade the GPU to a 3080 in the future I would probably do the PSU at the same time.
