Depends on what you are using the SSD for. I'm guessing that you will be installing the OS on it and some programs. A 120 GB drive formatted under NTFS and normal allocation size will only give you about 110 GB of usable space. Then, after installing Windows and doing all the updates, you'll have about 90 GB free. Unless this is the very last upgrade and the last bit of money you are willing to spend on your PC, I would get the the better 7970 GPU and then wait until I had enough to buy a 250 GB SSD. I recently picked up a 250 GB Samsung 840 for $160. If you are trying to make your games run better and faster, getting a 120 GB SSD won't really help as much as a top of the line GPU unless you have all your games installed on it. With only 90 GB free for games, you can probably fit 10 modern games on it. And, even then, the difference between a regular 7,200 RPM HDD and a SSD won't be very noticeable. The game will load a bit quicker, but once the game loads you will see no difference. Same thing in multiplayer, the maps will load a bit quicker but that is about it.
