What is the best gaming hardware I can get for my computer that will still be compatible with my system/motherboard/etc? It's pretty low tech so I'd rather not have something that will overheat my computer. If it gets too expensive though I'll probably just buy an Asus. Thanks for any help and my comp info is in the links below.
