Aspire E is a laptop but what specific model number is it? Like Aspire E1-571-6811. Most likely you have an integrated GPU meaning you can't replace it because it is in the CPU itself. Changing the CPU won't help because you don't have a place in the laptop to place you gpu anyways. You can try upgrades like faster and more RAM or try to overclock your GPU (Warranty may become VOID if the CPU breaks, try at YOUR OWN RISK).Other than that, you can't do much about it. Sorry.
Own a Predator Laptop? Then I bet you have learned a thing or two from beststevie. He has been helping out in this forum for quite a while and it's about time we recognized him for it. Thanks beststevie!
