If im gonna be upgrading the proccessor and ram should I just look for the cheapest cp possible with enough hard drive space?
-.- I have no idea what the other person is tellin you because honestly, they don't have a clue.
First off if you're gonna get a new processor, make sure the current motherboard you have is the right chip set, so that the processor you're about to buy will fit. If you really want that processor but it's a different chip set than your mother board you need to replace the motherboard.
Second, if you decided to replace the processor and the motherboard, you'll more than likely need to buy new RAM/Memory. Again you need to make sure that the RAM/Memory is gonna fit on that motherboard.
Third, if you get a new motherboard, you need to check what sort of power supply you'll need. Because the power supply you have might NOT work with the new motherboard. If not, you'll need to buy a new power supply with the correct cable. That cable is called, "ATX Power Connector" They come in 20 pin and 24 pin. Now a days motherboards use 24-pin and also come with an additional power connector for PCIe (express)
Fourth, you need to make sure that the video card you have will be compatible with the mother board, if the motherboard only has PCIe and not PCI and you have a PCI video card, you're gonna have to buy a PCIe video card. If you have AGP, get rid of it because PCIe > AGP. If you have a built in video card, in other words on board video card that's built into the motherboard, you will need to buy another video card that will be compatible with the motherboard.
And finally, now a days there's a lot of motherboard that only come with SATA (serial ATA) connectors. So if you have hard drive(s) that are ATA and you don't want to get rid of them, make sure the mother board not only have SATA (which is way better than ATA) but also has ATA connectors.
The best way to know what you should buy to upgrade your PC is by looking up the specs of your motherboard, since that is the hardware that everything has to connect to. If your motherboard is outdated, I would recommend you purchase a motherboard.
If you end up upgrading the whole system, you'll end up spending between $600-$1200 easily.
EDIT: And I just realized you're not building a new computer nor don't know how to install a processor, so I just wasted my time
