When I saw LTT video about the 69$ gaming pc returns I was wondering if it was actually worth it in my case. I currently own a prebuilt Lenovo ThinkCentre (which was free) which has an Intel Pentium E5400, 4Gb of ddr2 ram at 800mhz, some cheapo graphics card, a Kingston 250gb ssd and Windows 10 preloaded onto it. I wanted to know if I should invest in a GT 1030 which I found for 70$ from Gigabyte, a GTX 1050 from Gigabyte (199$) or simply not buy anything and just save up for an actual system. The goal would be to play some light esports titles at 1080p and maybe hopefully Overwatch (obviously over 30fps). I'm afraid that my CPU is not powerful enough since it's only at 2.7ghz and it's a dual core, therefore, creating a bottleneck with the GPU.
Please let me know if there's a graphics card worth buying and what fps I can expect to get.
Thanks in advance.
