Hi all, I have a some questions regarding the HP Envy 23. I have the model with the Core i7 3.1ghz and the nvidia geforce gt 540m. It runs games alright, but not the best, i only get about 20 - 30 fps on some games on medium (but i still get pretty reasonable fps on other games like cod and gmod). Would the reason for choppy framerates be because of the graphics card? Also, Is is possible to upgrade the graphics card with the all-in-one frame design? If this is not possible, would I be able to take the components out and put them in a case? Thanks
