Hello, this is my first time posting to this forum! I am planning on buying and upgrading an HP Compaq 8100 Elite SFF for school uses. I want this to be a budget build. The computer has an I-3 550. I want to upgrade the processor so I look up the computer on HP and I see that the computer had the option for an Intel Core i7-870 but next to it, it says "Requires a discrete graphics solution." I am guessing that it does not have integrated graphics so I scroll down and I see that some models of the HP Elite did come with graphics cards. I was looking at this graphics card ATI Radeon HD 4550 and I was wondering if it is pretty much plug and play same with the Intel i7? And is there a reliable and easy website that I can download the drivers. Here is the computer on the HP website- https://support.hp.com/us-en/produc...all-form-factor-pc/4098436/document/c02030592.
