Is the Intel T2080 good for gameing

dual cores are probably the most popular cpus currently purchased for gaming because of their value for money. You will have no trouble running recent games using a t2080 as long as you have a video card (or cards) that will take up the bulk of the video processing tasks required for games. for CPU benchmarks comparison see here

Note that the gpu/s will provide a lot more of the performance in games than the CPU because they have their own microprocessors and memory (commonly ddr3 and ddr4 - which is faster than the ram in your machine and is allocated specifically for processing visual information).
