My pc is core 2 duo 2.4ghz
Ram 6gb
Video card amd 5450hd 512mb but show video memory 2133mb
100 gb space left total 160gb har drive can i run gta 5 on these specs?
I ran it on C2D E8300, it was really slow, and about your GPU...
I had HD6770 which is better than yours, so my answer is no, you wont be able to run it.
