I have a HP Envy 700-230ea Desktop. Recently it crashed and my computer repair shop said it was due to my graphics card an AMD Radeon R9 270. They removed it and left me with the interior Intel graphics which has a peak resolotion of 1366x768 through a vga connection. I need a new graphics card. Should i get another AMD Radeon R9 270 or is there a more improved model that would be compatible with my desktop? Also where can i get one? I would be grateful for any help as my knowledge is limited. If anyone knows why the graphics card froze my desktop i would appreciate it.Thankyou.
