opengl is a major concern, it's the only reason i asked. That computer although well picked for the question, did not have all that i desired, but thank you for your efforts, it helped me ge on the right track.
i found something that may be exactly what i'm looking for, as i made mods for fallout new vegas and fallout 3 that made my dinosuar run those games without a problem by deleting half the lights and all the clutter that was non-essential for the game. here is the machine, i want to know through the gpu options if any supports open gl 3.3 or higher, also if it's better than this machine, which was my second choice:
https://www.newegg.com/Product/Product.aspx?item=1VK-0001-0BY86 ----> the one i'm considering to get.
https://www.walmart.com/ip/eMachines-750-GB-ET1331G-05w/13352323 -----> the 2ed option, it has many expasion slots
and if i can get a inside pic of the 1st option to see the motherboard, that would be great, thanks agian guys.
